In a world where rom-coms meet laboratories and chemistry isn’t just metaphorical, Ali Hazelwood has crafted her own literary genre of books: romance for the brilliant and bold. A neuroscientist by training and a romantic at heart, Hazelwood exploded onto the publishing scene with a refreshing voice that celebrates women in STEM, awkwardly lovable academics, and emotionally complex relationships.

Her protagonists are fierce, funny, and flawed in ways that make them achingly real, and her love interests are often grumpy with a gooey emotional center. If you’ve ever dreamed of love blossoming under fluorescent lab lights or amid a snowstorm of research rivalries, Hazelwood is the author for you.
This article is your comprehensive guide to the books by Ali Hazelwood, organized by standalone novels, series, paranormal entries, and novellas.

Standalone Novels (Contemporary Romance)
The Love Hypothesis (2021)
Ali Hazelwood’s debut novel, The Love Hypothesis, became an instant sensation—and it’s easy to see why. Olive Smith, a brilliant yet awkward PhD student, doesn’t believe in love, especially not for herself. But when she kisses a random man in the lab to convince her best friend she’s dating, she unknowingly plants one on the university’s notorious bad boy professor, Dr. Adam Carlsen. Surprisingly, Adam agrees to fake-date her for both their personal gains.
As their fake relationship plays out in university hallways and conference rooms, Olive finds herself questioning what’s real and what’s pretend. Hazelwood’s signature blend of sharp wit, academic banter, and deep emotional resonance makes this a standout. It’s a love story for every girl who’s ever felt like the smartest person in the room—but doubted whether she deserved to be loved. Among all Ali Hazelwood books, this one set the tone: smart women, real feelings, and chemistry you can’t fake.
Love on the Brain (2022)
Bee Königswasser is a neuroscientist obsessed with Marie Curie, justice, and… avoiding Levi Ward. So when she’s offered the opportunity to co-lead a cutting-edge NASA project—only to find out her co-lead is the very man who ghosted her in grad school—Bee’s not thrilled. But work is work, and she’s determined to succeed. To her surprise, Levi isn’t the brooding, arrogant man she remembers. He’s helpful. Supportive. Protective, even.
As they battle equipment failures, workplace sabotage, and lingering misunderstandings, Bee and Levi find themselves fighting off more than just scientific interference. Their chemistry sizzles, but so does their unresolved past. The enemies-to-lovers tension is electric, wrapped in workplace drama and STEM shenanigans.
Love on the Brain is pure Hazelwood—funny, feminist, and fiercely romantic. For fans of Ali Hazelwood books, it’s another reminder that sometimes, love grows best under pressure… especially when surrounded by robots and rocket science.
Love, Theoretically (2023)
Elsie Hannaway is a theoretical physicist with too many identities: dedicated adjunct professor by day, fake girlfriend-for-hire by night. When she interviews for her dream tenure-track position at MIT, she finds herself face-to-face with Jack Smith—the experimental physicist who once trashed her entire field and, unknowingly, her future.
What starts as academic animosity soon spirals into intellectual debates, grudging respect, and scorching tension. Jack is grumpy, brilliant, and unexpectedly perceptive. He challenges Elsie in ways no one else has. But as her many lies begin to unravel, she must choose between the version of herself others want—and the woman she really is.
With emotional vulnerability and fierce intelligence, Love, Theoretically proves Hazelwood’s gift for pairing high-stakes academia with heart-thudding romance. Among the most introspective of Ali Hazelwood books, it explores imposter syndrome, integrity, and what it truly means to be seen.
Check & Mate (2023)
In her YA debut, Hazelwood dives into the world of competitive chess—and complicated first love. Mallory Greenleaf once loved chess, but after it tore her family apart, she walked away. Years later, a charity tournament draws her back—where she stuns the world by defeating reigning champion Nolan Sawyer.
Suddenly thrust into the limelight, Mallory must decide if she’s ready to return to the game that betrayed her. Nolan is quiet, intense, and seems to carry emotional wounds of his own. As they clash across chessboards and continents, a slow-burning friendship (and maybe something more) begins to emerge.
Check & Mate is tender, fierce, and empowering—a coming-of-age story that fits perfectly among books by Ali Hazelwood, despite being aimed at younger readers. It’s about rediscovery, resilience, and trusting yourself after everything has fallen apart.
Deep End (2025)
Released in February 2025, Deep End dives into the pressure-cooker world of deep-sea research and forbidden love. Hazelwood introduces us to Dr. Arielle Sorenson, a marine engineer with a tragic past and a desperate need to prove herself. When she’s partnered with Grant Brennan—a gruff ex-submarine commander turned oceanographer—they must survive weeks in an underwater lab, tethered together by shared trauma and proximity.
As they navigate cramped quarters, deep-sea malfunctions, and media attention, the line between professional and personal begins to blur. But Arielle’s past threatens to sink her future—and the more she opens up to Grant, the more vulnerable she feels.
Deep End showcases a more emotionally intense, atmospheric side of Hazelwood’s writing. It’s claustrophobic, romantic, and ultimately healing. For longtime fans of Ali Hazelwood books, this is a deeper dive—literally and emotionally—into everything that makes her writing special.
Not in Love Series
Not in Love (2024)
Rue Siebert has never let anyone close—not since childhood abandonment taught her to depend only on herself. Now a fiercely accomplished structural engineer, Rue is focused on winning a high-stakes green-energy project grant. The only obstacle? Eli Killgore, the charming and aggravating rep from a rival firm who pushes every one of her buttons.
When they’re forced to collaborate on a sustainability initiative, sparks fly—and not the safe, environmentally friendly kind. What begins as workplace antagonism transforms into magnetic attraction and grudging respect. But Rue’s past is a fortress, and Eli’s patience may not be enough to tear it down.
Not in Love balances snark and sincerity, exploring vulnerability, trauma, and redemption in the language of spreadsheets and steel beams. As one of the newest Ali Hazelwood books, it’s mature, grounded, and emotionally potent—proving that love and logic can coexist, even in the messiest of hearts.
Problematic Summer Romance (2025)
Maya Killgore is twenty-three, a struggling grad student, and currently having a full-blown crisis—emotional, academic, and romantic. She’s been nursing an inconvenient and wildly inappropriate crush on Conor Harkness, a successful biotech executive… who also happens to be her older brother’s best friend. At thirty-eight, Conor is reserved, intimidating, and frustratingly dismissive. He insists their age gap is too big. Their dynamic too messy. The situation too… problematic.
But things take a steamy turn when they’re forced to spend a week together at a wedding in Taormina, Sicily. As their friends and families celebrate against a backdrop of sunlit ruins and volcanic cliffs, Maya and Conor share close quarters, unexpected moments, and the kind of chemistry that threatens to erupt like nearby Mount Etna. What begins as sharp banter and stolen glances turns into something riskier—and far more real.
Problematic Summer Romance is classic Ali Hazelwood: sexy, smart, and bursting with emotional tension. Set against the gorgeous Mediterranean landscape, it explores power dynamics, self-worth, and forbidden longing with warmth and depth.

Bride Series (Paranormal Romance)
Bride (2024)
Maia is a Vampyre-Human hybrid, orphaned young and raised on the margins of two societies that barely tolerate her existence. When she’s forced into an arranged marriage with Bram, the intimidating Alpha of the Northwest Werewolf Pack, Maia assumes the worst—domination, hostility, and violence. Instead, she finds herself entangled in a marriage that is equal parts political treaty and emotional minefield. Bram is unexpectedly thoughtful, gentle even, and loyal to a fault.
As Maia steps into her role as Alpha Mate, she must navigate internal pack politics, external threats from rival clans, and the dangerous power she’s only beginning to understand within herself. Meanwhile, Bram’s growing affection toward Maia evolves into a bond neither of them can deny. But trust doesn’t come easily when your world has taught you that love is weakness.

Mate (October 2025)
In this companion to Bride, Hazelwood shifts the focus to Serena Paris, a sharp-tongued Human-Were hybrid with no interest in pack politics—or in Koen Alexander, the infuriatingly composed Alpha of the Northwest Pack. But when a string of rogue attacks puts peace at risk, Serena is drawn into the very world she tried to escape. She and Koen must work together to uncover the threats—and survive the mounting tension between them.

STEMinist Novellas (2022)
Under One Roof
When Mara, a young and passionate environmental engineer, inherits half a house from her beloved mentor, she thinks it’s a lifeline. What she doesn’t expect? That the other half belongs to Liam, a moody, hyper-organized environmental lawyer who’s less than thrilled about sharing his home.

Ian, the one man she once let get close. The one she pushed away. As he embarks on a dangerous mission to rescue her, flashbacks reveal the complicated friendship and slow-burning chemistry they once shared—and the choice Hannah made that broke them apart.
