Book Overview: The Roommate Arrangement
Content Warnings: strong language, underage drinking, controlling parents, family drama
Summary: When Blair accidentally becomes college roommates with her brother’s best friend, sparks fly in this hilarious rom-com from bestselling author Samantha Markum, perfect for fans of Lynn Painter and Emma Lord.
Blair might be a little type-A, but she never thought of herself as completely overbearing…that is, until her two best friends drop her from their housing arrangement a week before her pre-college summer coding program is about to start.
Blair knows if she switches to an on-campus dorm, her parents will make her give up her expensive sculpture class with her dream mentor in order to pay for it. Desperate, she agrees to be the fifth roommate to four off-campus sophomores who are also in a last-minute bind. But things get complicated when one of her new roommates turns out to be her brother’s best friend, Jamie Atwater.
Blair begs Jamie not to tell her brother about the new living arrangement. Her brother would go straight to their parents, who would definitely not approve, and all her plans would fall apart. So they strike a deal: she’ll help him finish coding the app he’s building if he promises to keep her secret.
Spending more time together shouldn’t be a problem. Sure, Jamie has a new haircut, a mysterious tattoo, and a year’s worth of earned muscle, but it’s not like Blair is noticing. After all, they’re only roommates, right?

What happens when your new college roommate is also your big brother’s best friend? For Blair in Samantha Markum’s The Roommate Arrangement, it means chaos, comedy, and a secret she’s desperate to keep under wraps. Markum’s latest rom-com sets up a perfect storm of beloved tropes (think a forbidden crush colliding with the spark of an enemies to lovers dynamic, all wrapped in a story that manages to be both snarky and sincerely sweet). Fans of Lynn Painter and Emma Lord will feel right at home with Markum’s witty style and heartfelt moments. The Roommate Arrangement might just be the next campus love story you didn’t know you needed, and here are five reasons why this fresh, funny novel deserves a spot on your TBR!
The Forbidden Roommate Twist
Blair’s housing crisis throws her into a roommate arrangement she never saw coming. Dropped by her best friends at the last minute, she ends up moving in with a co-ed group of young adults (including Jamie, her older brother’s lifelong buddy). Awkward? Definitely.
The situation crackles with forbidden tension from day one. Blair knows her protective brother would freak out if he discovered she’s shacking up with his best friend, so she and Jamie agree to keep it their little secret. This means sneaking around their own apartment like they’re plotting a heist, all while pretending everything is perfectly normal. It’s the kind of delicious setup rom-com we adore: forced proximity with a big side of “we absolutely shouldn’t be doing this.” And as any seasoned reader can guess, that only makes the sparks between Blair and Jamie burn brighter.
Enemies-To-Lovers Sparks Fly
As if living with her brother’s buddy wasn’t complicated enough, Blair and Jamie have a knack for getting on each other’s nerves. She’s a planner with a streak of Type A perfectionism; he’s a laid back goof with a talent for pushing her buttons. Whether they’re sniping over who’s allowed to talk or bickering about the project they work on together, their banter is hilarious and crackling with chemistry.
It’s the classic enemies to lovers dance: every sarcastic quip and eye roll between them only highlights how much they care, whether they realize it or not. Jamie might drive Blair crazy, but there’s no denying that his new confidence (not to mention that mysterious tattoo and sudden gym gains) has her seeing him in a whole new light. Their back and forth gives the story a zippy energy full of “will they or won’t they” tension that keeps you eagerly turning pages.
Heartfelt Comedy, No Graphic Drama
One of the best things about this story is how it balances snark and sincerity. The Roommate Arrangement will have you snorting with laughter one minute and quietly saying “aww” the next. Markum keeps the tone light and upbeat even while Blair navigates real stresses like being ditched by friends and juggling parental expectations.
And crucially for those of you who prefer romance on the sweeter side, this book delivers all the swoon with none of the graphic detail. The chemistry sizzles through charged glances and playful flirting, but any intimate moments stay firmly behind closed doors. It proves you can have a romantic, engaging story without veering into explicit territory.
Plus, the comedic set pieces are gold: imagine Blair and Jamie scrambling to hide any evidence of cohabitation during a surprise visit, or bonding over late night coding sessions as part of their secret pact. The result is a rom-com that feels both modern and wholesome, like your favorite teen movie come to life on the page!
Chosen Family Vibes
Beyond the swoony romance, this novel celebrates the power of found family. When Blair moves in, her new roommates start off as near strangers (Jamie aside), but it doesn’t take long for this ragtag group to gel into a tight knit crew.
The banter and bonding in the shared house feel authentic, whether it’s the late night junk food feasts or everyone teaming up to play DND in their cramped living room. Each roommate brings a unique vibe to the mix, and soon they’re all looking out for one another.
Blair might have arrived feeling abandoned by her old friends, but she gradually discovers that sometimes family isn’t just the people you’re related to. It’s the people who have your back when things get tough. The Roommate Arrangement nails that heartwarming “friends who become family” dynamic, leaving you wishing you could hang out in their off campus living room too.
A Heroine Who Breaks The Mold
Blair herself is a huge part of what makes this book special. She’s not your typical rom-com leading lady, and that’s exactly why we love her. For one, it’s refreshing to see a heroine who isn’t a size two.
Blair is midsize (more like a real person than the usual super skinny YA protagonist), and the story treats this as perfectly normal, which is wonderful to see. There’s no cliché makeover or dramatic weight angst; Blair is confident, creative, and focused on her goals from day one. She feels real, from her nerdy passion for coding and art to the way she sometimes overthinks and gets in her own way.
Who hasn’t been a little bossy with friends or freaked out about a big life change? Blair’s relatable flaws and strengths make her easy to root for. By the end, you’re cheering not just for the romance, but also for Blair to embrace her authentic self and chase the dreams she’s worked so hard for!
A snarky yet sweet rom-com gem that delivers hilarious moments, heartfelt warmth, and a refreshingly real plus-size heroine to root for!
