Books like The Love Hypothesis

Helen Hoang's The Kiss Quotient is the closest match to The Love Hypothesis in terms of tone, tropes, and readership. Stella Lane is an econometrician with Asperger's who hires an escort named Michael Phan to teach her about physical intimacy, and the professional arrangement becomes something neither of them planned for. Like The Love Hypothesis, the novel features a heroine in a quantitative field whose approach to relationships is shaped by her analytical mind, and the fake-dating setup creates the same delicious tension between what the characters say they want and what they actually feel.

Hoang writes with warmth and specificity, particularly about Stella's neurodivergence, which is depicted with care and accuracy rather than as a quirky character trait. Both novels pair brainy heroines with love interests who are patient, attentive, and genuinely interested in their partners' inner lives. The steam level is higher than Hazelwood's, but the emotional core is the same: two people learning to trust each other through honesty and vulnerability.

If The Love Hypothesis was your gateway into contemporary romance, The Kiss Quotient should be your next stop.

Love on the Brain is Hazelwood's second novel and shares The Love Hypothesis's DNA in every way that matters. Bee Königswasser, a neuroscientist, is assigned to co-lead a NASA project with Levi Ward, a man she has clashed with since graduate school. The enemies-to-lovers setup is familiar, and Hazelwood executes it with the same blend of nerd humor and genuine feeling that made her debut work.

Like The Love Hypothesis, the novel puts its heroine in a professional environment where she must fight for respect while navigating a growing attraction to someone she thought she hated. The STEM setting is even more specific here, with NASA providing the backdrop and brain science providing the metaphors. Bee is louder and more combative than Olive, which gives the banter a different flavor, but Levi shares Adam Carlsen's quiet intensity and hidden tenderness.

Both novels treat scientific work as a legitimate source of identity and satisfaction, not just a backdrop for romance. If you loved The Love Hypothesis, this is more of what you want from the same voice.

Sally Thorne's The Hating Game is one of the books Hazelwood has cited as an influence, and the connection is obvious. Lucy and Joshua are executive assistants at a publishing company who spend their days engaged in elaborate competitive games that barely disguise their mutual attraction. Like The Love Hypothesis, the novel runs on the energy between two people who cannot stop paying attention to each other, and the office setting creates a natural arena for their push-pull dynamic.

Thorne writes banter at the same speed Hazelwood does, and the shift from antagonism to vulnerability follows the same arc. Both novels feature tall, intimidating male love interests whose severity hides real emotional depth, and both heroines are underestimated by their professional worlds. The Hating Game is lighter on the STEM angle but heavier on the workplace politics, and the pacing is tighter, with the romantic tension building in a more confined space.

This is the book that helped establish the template Hazelwood works within, and it remains one of the best examples of the enemies-to-lovers workplace romance.

Elena Armas's The Spanish Love Deception follows Catalina Martin, who agrees to bring her tall, infuriating coworker Aaron Blackford as a fake date to her sister's wedding in Spain. The fake-dating premise mirrors The Love Hypothesis directly, and Armas writes the slow thaw from irritation to attraction with the same patient attention Hazelwood brings to Olive and Adam.

Both novels feature heroines who are funny, self-deprecating, and carrying more emotional weight than they let on, and both male love interests are the strong-silent type whose actions speak louder than their words. The Spanish setting provides a change of scenery from Hazelwood's Stanford campus, and the family dynamics at the wedding add pressure that the academic setting does not.

Armas writes with warmth and accessibility, and the length of the novel, longer than most rom-coms, gives the relationship room to develop at a realistic pace. Readers who loved the slow-burn tension and the grumpy-sunshine dynamic of The Love Hypothesis will find The Spanish Love Deception scratching exactly the same itch.

Christina Lauren's The Soulmate Equation puts a STEM spin on the matchmaking premise: Jess Davis, a single-mom statistician, discovers that a DNA-based dating company has identified her as a 98-percent match with its founder, Dr. River Pena. Like The Love Hypothesis, the novel treats its scientific premise with just enough seriousness to ground the romance, and the heroine's quantitative mind creates both comedy and genuine insight into how she processes relationships.

Jess and River's forced proximity as she participates in the company's study mirrors Olive and Adam's fake-dating arrangement, and the slow shift from skepticism to genuine connection follows the same emotional trajectory. Christina Lauren writes with the same accessible warmth Hazelwood brings to her work, and the single-mom subplot adds a layer of real-world complication that raises the stakes beyond the typical rom-com formula. The science is lighter than Hazelwood's, more pop than academic, but the respect for smart women and their work is identical.

This is a strong pick for readers who want the STEM-romance combination in a slightly different flavor.

Emily Henry's Beach Read is not a STEM romance, but it shares The Love Hypothesis's structural DNA and emotional intelligence. January, a romance writer in crisis, and Augustus, a literary fiction author, challenge each other to write in the other's genre, creating a framework for two stubborn people to gradually reveal themselves to each other.

Like The Love Hypothesis, the novel pairs a heroine dealing with real grief and self-doubt with a love interest whose intimidating exterior hides genuine tenderness. Henry writes banter at Hazelwood's level, and the professional rivalry between January and Augustus creates the same charged atmosphere as Olive and Adam's academic interactions.

Both novels take the romance genre seriously as a space for emotional complexity, and both feature heroines whose career identities are central to who they are. The Michigan beach setting gives the novel a different atmosphere than Hazelwood's Stanford, but the core appeal, smart people falling for each other while pretending they are not, is identical.

Abby Jimenez's The Friend Zone takes the romantic comedy template and adds real stakes: Kristen falls for Josh while carrying a secret about a medical procedure that may make it impossible for her to have children. Like The Love Hypothesis, the novel features a heroine whose humor and self-deprecation mask genuine pain, and the central obstacle to the romance is not a misunderstanding but a real, unresolvable conflict between what two people want from life.

Jimenez writes with the same accessible warmth Hazelwood brings to her characters, and Josh's patient, devoted love for Kristen echoes Adam Carlsen's quiet devotion to Olive. Both novels refuse to reduce their heroines to romantic archetypes, insisting that their internal conflicts matter as much as the love story.

The supporting cast is vivid and funny, providing the same kind of friend-group energy that Olive's lab mates bring to The Love Hypothesis. This is a book for readers who want the humor and heat of Hazelwood's work combined with a central conflict that has no easy answer.

Emily Henry's People We Meet on Vacation is the obvious next pick if I want the same swoony, banter-heavy energy The Love Hypothesis runs on. Poppy and Alex have taken a summer trip together every year for a decade, until two summers ago when something happened that ended the friendship.

The book alternates between the present, where Poppy convinces Alex to take one more trip, and flashbacks through every summer they spent as best friends pretending neither of them was in love. Henry writes Poppy's voice with the same self-aware, panicky charm Hazelwood gives Olive, and the will-they-or-won't-they engine is just as ruthless.

Recommended for Love Hypothesis readers who want the slow-burn payoff stretched across ten summers and a wedding instead of one fake-dating contract, with the same sparkly first-person banter every page.

Christina Lauren's The Unhoneymooners is the fake-dating romcom that hits every Love Hypothesis pleasure point in a different costume. Olive Torres and Ethan Thomas hate each other, but when their siblings' wedding ends in mass food poisoning and the bride and groom can't take their all-expenses-paid Maui honeymoon, the two only sober guests get sent in their place.

They have to play newlyweds for ten days. The premise asks the same question Hazelwood asks: what happens when two people who refuse to admit anything get forced into proximity and a public-facing lie?

Lauren writes the same steamy-but-tender register, with Olive narrating in first person with a sense of humor as dry as Olive Smith's. Recommended for readers who want the fake-dating beats with a sun-soaked vacation backdrop and a slightly older, slightly snarkier heroine.

Casey McQuiston's Red, White & Royal Blue is the queer fake-dating breakout that took off the same year as The Love Hypothesis and earned the BookTok comparison the day it hit shelves. Alex Claremont-Diaz, son of the first woman President, hates Prince Henry of Wales until a wedding-cake disaster lands them on every front page in the world and their two governments invent a fake friendship to manage the press.

The fake friendship turns into something neither of them can keep hiding. McQuiston writes the same swoony, banter-first energy Hazelwood does, scaled up to international politics, with email exchanges and group chats that rival anything in the lab-meeting scenes of The Love Hypothesis.

Recommended for readers who want the fake-relationship machinery with a Prince Henry instead of an Adam Carlsen, and a movie adaptation already streaming.

Talia Hibbert's Get a Life, Chloe Brown is the romance Love Hypothesis readers should know about but somehow keep missing. Chloe Brown is a 31-year-old computer geek with fibromyalgia who, after a near-death cycling accident, decides to write a "get a life" list and rope her tattooed superintendent Red Morgan into helping her check items off.

Hibbert writes the same first-person heroine voice Hazelwood does, with the same self-deprecating intelligence and on-page anxiety that made Olive feel real. The chronic-illness representation is woven into every scene without ever making the book about illness, and Red is a grumpy artist with a soft heart who gives Adam Carlsen a run.

Hidden gem because the British contemporary scene is still under-covered on US BookTok. Recommended for readers who want the same prickly, smart heroine in a romcom that takes mental and physical health seriously.

Talia Hibbert's Act Your Age, Eve Brown closes the Brown Sisters trilogy and gives Love Hypothesis readers another heroine-meets-impossible-grump pairing. Eve Brown crashes her car into the bed-and-breakfast owner Jacob Wayne, a control freak in the middle of a hiring crisis, and ends up working as his chef while he hates every second of her existence.

Both characters are coded autistic, and Hibbert writes the dynamic without ever making the neurodivergence the conflict, just the lens through which two stubborn people misread each other. The same enemies-to-lovers slow burn The Love Hypothesis ran on the second time around, with the same kind of romantic obliviousness Olive shows.

Hidden gem because the third-in-series tag means readers who didn't grab the first two often skip it entirely. Recommended for readers who want a chaotic-good heroine paired with a Type-A grump.

Alison Cochrun's The Charm Offensive is the queer romcom Love Hypothesis readers will swallow in a weekend and immediately recommend to a friend. Charlie Winshaw is the disgraced tech founder cast as the new lead on a Bachelor-style reality show called Ever After, and Dev Deshpande is the romantic producer assigned to coach him into falling for his contestants.

Charlie's anxiety, OCD, and depression are written with the same care Hazelwood gives Olive's interiority, and the public-facing fake romance machinery hits every fake-dating beat from the inside. Cochrun's debut moves at a Hazelwood-tempo slow burn and pays it off with a swoon every fan of the lab-bench kiss is chasing.

Hidden gem because reality-show-set romcoms get sorted into "rom-com" rather than "BookTok romance" on shelves. Recommended for readers who want the same heart inside a queer second-chance frame.

Emily Henry's Funny Story, released April 2024, is the fake-dating romcom Love Hypothesis readers were waiting for from the queen of contemporary romance. Daphne is a Michigan children's librarian whose fiance Peter dumped her for his lifelong best friend Petra, and now Daphne is sharing an apartment with Petra's ex-boyfriend Miles, a flannel-wearing wine-bar guy who is everything she is not.

They cook up a fake-dating plot for Peter and Petra's wedding. Henry writes the same swoony first-person voice Hazelwood uses, with the same panic-spiral comedic interior monologue Olive Smith narrates in.

Released April 2024 and instant New York Times number one. Recommended for readers who want the freshest entry in the fake-dating canon from one of the best practitioners working, with a small-town summer setting that hits every Love Hypothesis vacation-romance beat.

Ashley Poston's The Dead Romantics, released June 2022, is the BookTok smash that gave Love Hypothesis readers a paranormal-tinged romcom with the same heart. Florence Day is a ghostwriter who has lost her belief in love after a breakup, and her demanding new editor Ben Andrews has refused her latest deadline extension. Then Ben dies.

Then Ben's ghost shows up at the funeral home Florence's family runs in South Carolina, asking for her help figuring out what unfinished business is keeping him here. Poston writes Florence in the same self-aware, lovesick first-person register Hazelwood gives Olive, and the second-half romance is as tender as anything in the lab-bench canon. Released June 2022 and one of the breakout BookTok romances of that year.

Recommended for readers who want a funny, weepy, ghost-adjacent twist on the workplace-romance format.
