To go there or not to go there.
That is the dilemma facing little sisters in the romance book world who desperately fall for their older brother’s best friend. And vice versa.
It’s pretty hard to resist the temptation when he’s right there, hanging with your brother and just too good to be true.
Am I right?!
I adore the brother’s best friend romance trope because it offers so much.
You can get a sweet, slow burn, friends to lovers story if it’s an unrequited love romance.
Or maybe you get a book full of angst because the brother’s best friend is truly off-limits creating a tantalizing forbidden romance.
Or perhaps it morphs into a second chance love story because one night the little sister and best friend cross the line but are later torn apart only to reconnect years later.
Gah! The options are endless and oh so good, which is why this fun romance trope is not only one of my favorites but a popular one among romance book readers as well.

My Favorite Brother’s Best Friend Romance Books
Beautiful Player
by Christina Lauren
When Hanna Bergstrom receives a lecture from her overprotective brother about neglecting her social life and burying herself in grad school, she’s determined to tackle his implied assignment: get out, make friends, and start dating.
And who better to turn her into the sultry siren every man wants than her brother’s gorgeous best friend, Will Sumner, venture capitalist and unapologetic playboy?
Will takes risks for a living, but he’s skeptical about this challenge of Hanna’s…until the wild night his innocently seductive pupil tempts him into bed- and teaches him a thing or two about being with a woman he can’t forget.
Now that Hanna’s discovered the power of her own appeal, it’s up to Will to prove he’s the only man she’ll ever need.
Hanna and Will are two of my favorite characters and one of my favorite romance book couples.
She is this super smart woman but looking for a wingman to show her the seductive ropes. Despite being her brother’s best friend, it doesn’t take Will long to give in to her and change his ways.
I loved the “realness” of their relationship and just how seamlessly they fit together. It’s one of Christina Lauren’s best and one of the brothers’ best friend romance books I highly recommend!
To Love Jason Thorn
by Ella Maise
Jason Thorn is my brother’s childhood friend and was my first crush until he crushed my heart to pieces and moved away.
Now he is a movie star, the one who makes women of all ages go into a screaming frenzy.
And he’s back, about to star in a new movie inspired by the book I wrote. How am I to survive this?
This was such a sweet book! When Olive and Jason meet up again, Jason has an image problem and his people think he should get married and Olive appears to be the best candidate.
Though Olive has always loved Jason, she didn’t come across as a sap to me but a kind, sweet woman despite putting her heart on the line to save his image.
This was a great, slow burn romance between a brother’s best friend and the girl he never knew loved him.
Until Fountain Bridge
by Samantha Young
Ellie has been in love with Adam Sutherland for as long as she can remember.
What started as a childhood crush on her older brother’s best friend soon bloomed into full-blown infatuation.
Unfortunately, it also meant full-blown heartache, as Adam refused to fall for Braden’s little sister.
But it took a crisis to make Adam realize he’s wasted too much time denying his feelings for her.
Now happily settled with the woman he’s pined after for years, he’s about to find out what their ten-year courtship was like for her, through the journals she kept during their ups and many downs.
While this brother’s best friend romance is a novella, it totally hit the spot and is a favorite of mine.
You come to meet Ellie and Adam in Young’s On Dublin Street (a definite must-read!), but I loved how you see behind the scenes of their developing relationship in Ellie’s journal entries in this brother’s best friend romance book.
What came to be almost wasn’t but luckily love prevailed in the end!
Make Me Yours
by Melanie Harlow
Cheyenne has been in love with her brother’s best friend for years but he was always the man she couldn’t have. All it took was one accidental text to let her crush out of the bag.
Now she’s finally with the man of her dreams but is he willing to put his heart on the line again, for her?
You are going to love this story about Cheyenne and Cole. The build-up to their relationship was filled with such tension and that text message – OMG!
This brother’s best friend romance book is also a cute, neighbors to lovers, single dad story. It’s one of Harlow’s best. My Review.
Ugly Love
by Colleen Hoover
When Tate Collins meets airline pilot Miles Archer, she doesn’t think it’s love at first sight. They wouldn’t even go so far as to consider themselves friends.
The only thing Tate and Miles have in common is an undeniable mutual attraction.
Once their desires are out in the open, they realize they have the perfect set-up. He doesn’t want love, she doesn’t have time for love, so that just leaves one thing.
Their arrangement could be surprisingly seamless, as long as Tate can stick to the only two rules Miles has for her.
They think they can handle it, but realize almost immediately they can’t handle it at all.
Hearts get infiltrated. Promises get broken. Rules get shattered. Love gets ugly.
I love how this book starts with a bit of instant attraction between two struggling characters that becomes one of the greatest slow burn romances.
Despite Miles being her brother’s best friend and fellow pilot, they establish a neighbors with benefits relationship that they try and keep separate from any feelings.
It’s a great look at how love gets in the way but how it can also truly help heal. My Ugly Love Review.
Rebel Roommate
by Jeannine Colette and Lauren Runow
When Stacey transfers to UC Berkeley, she moves in with her brother, but she also inherits another roommate, her brother’s best friend, Wesley Knight.
Wesley was the boy who constantly teased her growing up and now he’s the fun police by scaring off any guys who want to talk to her.
If he’s ruining her dating life then she can do the same to his.
Yet when she turns up the flirting, the line between roommates becomes blurred and has them breaking all the rules.
This was a fun, brother’s best friend romance book with the added tension between roommates!
I loved how Wesley hid his feelings behind wanting to “protect” her from any other boy on campus though the heat turned up once Stacey turned the tables on him.
A great new adult romance to check out in this romance category! My Review.
Next in Line
by Amy Daws
What happens when the cute mountain man you made out with in an ice fishing shack turns out to be your brother’s best friend?
A whole lot of awkward, that’s what.
Maggie’s mind is reeling when she discovers the guy she became tangled up with at Marv’s Bait & Tackle isn’t a stranger like she thought.
The big snag: Sam and Maggie’s chemistry is hot enough to melt ice, which makes keeping their secret far more difficult than either expected.
I seriously adore anything Amy Daws writes and this one was no different. I loved how this started out with Maggie having no idea that Sam was her brother’s best friend!
With a lot of sneaking around and ice fishing shenanigans, you’ll devour this brother’s best friend romance book in one sitting.

Fix Her Up
by Tessa Bailey
Georgette Castle’s family runs the best home renovation business in town, but she prefers planning parties and making people laugh so no one really takes her seriously.
Georgie’s determined to fix herself up and finally go out on a date, but nobody’s asking the town clown out for a hot night.
To help change up her image, she turns to her brother’s best friend, Travis Ford.
Travis was major league baseball’s hottest rookie when an injury ended his career. Now he’s flipping houses to keep busy and trying to forget his glory days.
When Georgie proposes a wild scheme—that they pretend to date, to shock her family and help him land a new job—he agrees. What’s the harm?
But the girl Travis used to tease is now a funny, full-of-life woman and there’s nothing fake about how much he wants her.
I LOVE fake relationship love stories because they have the best tension and angst.
Throw in a secret crush on a brother’s best friend and you’ve got one HOT and steamy romance book that only Bailey can deliver.
I love how Georgie’s determination to change her reputation forces her to confront her crush on Travis. It’s oh so good!
The Secret to Dating Your Best Friend’s Sister
by Meghan Quinn
How do you date your best friend’s sister? Easy.
First pretend that you want her to set you up with someone else. That will bring the two of you closer.
Go on date with lots of random women, proceed to get stupid drunk and talk about your best friend’s sister, thus gaining the courage to finally make a move.
Then randomly show up at her apartment and confess your love. At least–that’s what I thought was going to happen.
But my attempts to win over Julia Westin backfired in more ways than I can count.
She’s smart and definitely not interested in games, my gifts, or my stories. She might want me too; but she’s not giving in that easy.
Get ready for some great banter and a really fun brother’s best friend romance book that only Meghan Quinn can deliver.
I love how it’s the brother’s best friend who is chasing after the sister in this romance rather than the other way around. It’s a great twist on this trope that I think you’ll really like.
Twisted Love
by Ana Huang
Driven by a tragedy that has haunted Alex Volkov for most of his life, his ruthless pursuits for success and vengeance leave little room for matters of the heart.
Ava Chen is a free spirit trapped by nightmares of a childhood she can’t remember.
But despite her broken past, she’s never stopped seeing the beauty in the world, including the heart beneath the icy exterior of a man she shouldn’t want.
Her brother’s best friend. Her neighbor. Her savior and her downfall.
Theirs is a love that was never supposed to happen—but when it does, it unleashes secrets that could destroy them both…and everything they hold dear.
So typically brother’s best friend romance books involve heroes who are fun, sweet, and nice. Well, not this hero.
If you want a book with a possessive, antihero alpha then this is the choice for you. This is an opposites attract, steamy read. Just gear up to meet Alex. You’re going to need to.

Waylaid
by Sarina Bowen
Daphne Shipley doesn’t understand why Rickie keeps flirting with her, especially since he stood her up all those years ago.
Only now that their paths have crossed again and he’s living in her house, working on her family farm, he doesn’t seem to remember the six hours they spent together.
We’re both keeping secrets, even if he can’t remember his, but that doesn’t mean we should help each other, or kiss each other, does it?
Oh, poor Daphne – you totally fall for your brother’s best friend, then not only does he stand you up and ghosts you but then he doesn’t even remember you when you see him again!
Well, cut Rickie some slack, there is a valid reason and you’ll totally fall for him in this one because he’s such a great guy.
This also has a bit of mystery to it, which I wasn’t expecting but interesting to learn more about Rickie.
Could Have Been Us
by Corinne Michaels
Fifteen years ago, I fell for Jack O’Donnell.
I was just a girl, but I knew my brother’s best friend was the only man I’d ever love.
On my eighteenth birthday, when I asked him to kiss me, I never imagined it would change my life so completely.
I gave Jack everything that night.
In order to move on, we had to go our separate ways and pretend like nothing happened, but even that wasn’t as heartbreaking as the secret we were forced to keep.
This brother’s best friend romance book definitely fits in the angsty camp! What starts out as a one-night stand will forever follow Jack and Stella.
But this is truly a second chance romance with all the small-town feels that will have your heart breaking but then lifting all the same.
Playing for Keeps
by Kendall Ryan
My teammate’s incredibly sweet and gorgeous younger sister should have been off-limits, but my hockey stick didn’t get that memo.
After our team won the championship, our flirting turned physical and I took her to bed. Shame sent her running the next morning from our catastrophic mistake.
She thinks I don’t remember that night—but every detail is burned into my brain so deeply, I’ll never forget.
I have one shot to show her I can be exactly what she needs, but Elise won’t be easily convinced.
That’s okay, because I’m good under pressure, and this time, I’m playing for keeps.
Yes! A hockey romance!
You don’t have to twist my arm to read a great sports romance, but when a teammate and best friend falls for the little sister, things get interesting.
I love how Justin and Elise have known each other for a while as it helped to understand why Justin wasn’t giving up on making her his!
Fair Catch
by Kandi Steiner
As if things aren’t already tough enough as the only girl on a college football team, Coach had to go and assign Zeke Collins as my roommate.
A cocky kick returner and my brother’s best friend who should have been ripped of that title years ago, he’s as infuriating as he is hot.
He thinks because we grew up together that it’s his role to protect me, but all he does is get in my way, make me look weak, and make me hate him more.
I’m the only girl in collegiate football. The pressure doesn’t get to me.
But sharing very thin walls with Zeke Collins? I wasn’t prepared for that.
And the more we’re forced together, the harder it is to distinguish that pencil-thin line between hating him… and wanting him.
OMG this brother’s best friend has everything I love: enemies to lovers, football, and a forced proximity romance. EEK!
I’m all in and can’t wait to see the sparks that fly between these two.
Plus, give me a strong heroine any day and I’m so there with this romance.
Rookie Move
by Riley Hart and Neve Wilder
McRae has had a crush on his brother’s best friend since the moment he laid eyes on him four years ago.
Warner Ramsey is 225 pounds of pure hotness, a media darling, and one of the best NFL quarterbacks in the league.
It was easy to keep his crush under control when he was in college. Now, they play for the same team, and he should be focusing on dominating his rookie year, not crushing on his teammate.
Besides, Ramsey’s straight.
Who’s up for a MM brother’s best friend romance book because this is definitely the one to check out.
I love that both of these characters are bi and play professional sports.
When Neve Wilder and Riley Hart, two of my favorite MM romance writers, said they were teaming up, this was an instant add to my TBR list and it should be for you as well.
Come to Me Quietly
by A.L. Jackson
Aleena Moore is haunted by Jared Holt. It’s been six years since she’s seen her brother’s best friend, the self-destructive bad boy she secretly loved in high school.
As the years pass, she knows it’s time to move on.
But just when she opens her heart to her friend, Gabe, Aly returns home to find Jared sleeping on her couch.
Covered in tattoos and lost in rage, he’s begging to be saved from his demons—the memories of the day he destroyed his family.
As the two reconnect, their passion is hot enough to torch Aly’s judgment. But can she risk her future for a man who lives on the edge of destruction?
This is one of Jackson’s popular, earlier works, and with good reason.
I’m kind of a sucker for the brother’s best friend romance books where the best friend tries his best to steer clear of the girl because he doesn’t feel he’s good enough for her.
He may want to make a move on his best friend and now roommate’s sister, but he’s going to have to work through some baggage first.

What may have started as a crush for Carina, Max is going to have to work hard to get back in her good graces once he realizes he wants to keep her and marry her.

Fearless King
by Maya Hughes
The butterflies in my stomach turned into full-blown eagles the second our lips touched. A kiss under the stars that changed our relationship forever.
After a lifetime of wishing, I stared up into Ford’s eyes with his fingers caressing my cheek and my heart racing.
The evening ended with my heart bleeding on the ballroom floor.
He destroyed my heart two years ago, but now he wants back in my life.
I thought I was over him. But with one text, in the middle of the night, I know I’m in over my head.
Got to give it to Liv. Who can resist when your crush texts you “I need you.”?
This is a brother’s best friend romance book but I’d also fit it in the second chance, slow burn category for all that Liv and Ford go through.
Through in a little family drama and you’ve got one heart-aching romance worth reading.
Wait for Me
by Tia Louise
Taron Rhodes was my brother’s best friend.
I gave him my first real kiss, my heart, my everything. I said I’d wait for him.
I’m still waiting, because Taron Rhodes is still the man of my dreams. And I have a secret that has his blue-green eyes.
Noel LaGrange stole my heart when she was only eighteen.
Everything changed when Sawyer and I joined the military. We were honorably discharged, but I didn’t go to her.
I broke her heart just as surely as I broke mine, but I’m going back to make it right. If she’s still waiting…
I’m not usually one to go for books with the secret that this one implies, but then again when you get a struggling hero who’s a military man, I change my tune.
If you too like wounded souls, check out this brother’s best friend romance book with a sweet second chance romance.
Bad Habit
by Charleigh Rose
I was infatuated with Asher Kelley the moment he came tumbling through my brother’s window five years ago.
As I got older, harmless flirting turned to stolen moments in dark corners. Until one day, he was gone without a trace.
Now, three years later, he’s back. Callous and cruel. He’s my brother’s best friend. My parents’ worst nightmare.
I should hate him. But like a bad habit, I can’t quit him.
I admit that I’m obsessed with the Bad Love series by Rose and this is the book that started it all!
If you love new adult, brother’s best friend romance books, then give Asher and Briar’s story a go.
Asher is another one of those struggling heroes who is holding a grudge against Briar and we don’t initially understand why.

But when an unforeseeable series of events sends Phoebe stumbling headfirst into danger, there’s only one man who can protect her. Though, in his quest to save her life, he may just break her heart.
What do you do when the woman you want is the person you can’t have? Oh Nate, if only you knew!

by Susannah Nix
Wyatt King isn’t looking for love because he’s already found it. Too bad she’s off-limits.

Until the night an accidental kiss blows the lid off those feelings they’ve both kept buried.

The Crush
by Penelope Ward
It’s natural to want the one you can’t have. And for as long as I could remember, I’d secretly wanted my brother’s best friend, Jace.
Now in our twenties, Jace has moved in with my brother, Nathan, and me to help us make ends meet after our parents died.
Living under our roof, Jace was as bossy and protective as ever. But he certainly didn’t look at me like a sister anymore.
Finally, we gave in but we have to be careful not to get caught.
I haven’t yet read this one but it fits the brother’s best friend romance of forbidden love, with a side of broken trust, and an unexpected second chance.
Sleeper
by Kayley Loring
My stress level is off the charts. I can’t sleep right on a normal day, and lately my days are filled with the best kind of chaos.
I’ve had to step it up as the young single dad to my two kids while my ex is away but our nanny just quit.
The only person I could trust to hire as a temp nanny is my best friend’s sister.
Willa is fresh out of grad school and my kids adore her.
I couldn’t sleep last night because she wasn’t here. Turns out I can’t sleep unless she’s in my house now.
If my friend had any idea what I want to do to his gorgeous troublemaker of a sister, he would smother me with a pillow.
The chances of us succeeding as a couple are not great but it’s a chance I’m going to take.
I love Kayley Loring’s books because they are just so fun and unique. I find her characters to be hilarious and quirky and they always deliver a happily-ever-after.

by M. Mable and Aly Martinez
Hudson Bradley is the cockiest, most stubborn, hard-headed man I’ve ever known. And for fifteen years, he’s been my brother’s best friend.
But lately, what I’m feeling for him isn’t friendship at all.
Why is my heart racing every time his blue eyes lock on mine? Why does every word he rumbles in my ear make my body come alive?
And worst of all, why did I bet him that I could find a woman he and his son would both love?
If I hadn’t given up on love altogether, Hudson would have been perfect for me. After all, he was there the day my world fell apart. He’s spent the last six years piecing me back together.
Now that the time is right, I have to make him mine—before I lose him forever.
I love that this is a brother’s best friend romance book where the woman is ready to go after her man.
This is a friends to lovers romance with all the feels and a good slow burn that should earn a spot on your TBR pile.
The Bookworm’s Guide to Dating
by Emma Hart
All I want for my birthday is books but what I got was my brother’s best friend playing matchmaker.
I’ll humor him and go on the dates but all I really want is him.
A heroine who loves books? I’m in. Enough said 😊
I do enjoy a good “let me fix you up” romance when really one of the main characters just has to open their eyes and see what’s in front of him.
In this case, I hope Kinsley doesn’t have to wait long for Josh to get the message!
This is War
by Kennedy Fox
Travis King is the worst and I hate him. It wouldn’t matter so much if he were avoidable.
But considering he’s my older brother’s best friend and roommate, I see him more than I’d ever want to.
Even though I’ve had a crush on him since I was ten, the feelings weren’t mutual and he’s made that very clear.
He’s always loved getting under my skin and one night against my better judgment, I let him in my bed.
I love a good, enemies to lovers story and this one sounds delightful!
Bring on the dirty talking banter and all the steamy scenes in this one which is book one in a duet.
Power Plays and Straight As
by Eden Finley and Saxon James
My brother asked me to keep an eye out for his best friend on campus and keep my hands to myself.
Even if Zach is a quintessential nerd, who I’ve always thought was cute, I don’t have the time to think with my … stick.
There’s only one stick I should be focused on this year, and that’s my hockey stick. My goal once I graduate is to get an NHL contract.
Only, keeping to the rules is harder than I thought it would be.
Give me any romance book with a cute nerd!
Though I love Foster as the hockey hunk, I’m all about Zach, in this brother’s best friend romance book as he’s still carrying his V-card.
Check it out if you love gay romance novels.
