Overview
This five-book paperback set gathers Ali Hazelwood's most beloved contemporary romances for fans of witty, science-driven love stories. Spanning physics labs, PhD programs, neuroscience labs, biotech boardrooms, and competitive swim decks, each novel follows a brilliant, career-focused heroine who discovers chemistry isn't confined to the classroom. Hazelwood pairs sharp banter and academic humor with genuinely swoony slow-burn tension, cementing her place as a defining voice in STEM romance. Whether readers start with fan-favorite The Love Hypothesis or newer release Deep End, this set delivers five satisfying, emotionally rich reads together.

About the Books
Across these five novels, Ali Hazelwood builds a loosely connected romance universe unified by brainy heroines, workplace tension, and hard-won happy endings. Love Theoretically follows Elsie Hannaway, an adjunct physicist juggling multiple identities and job interviews until her carefully separated worlds collide. The Love Hypothesis, Hazelwood's breakout debut, centers on PhD candidate Olive Smith, whose fake relationship with a notoriously prickly professor grows uncomfortably real. Love on the Brain sends neuroscientist Bee Königswasser into a rivalry-turned-romance with a former colleague while she works on a high-profile brain-machine-interface project. Not in Love shifts into the corporate world, where biotech engineer Rue Siebert finds herself drawn to the man leading a hostile takeover of her company. Deep End, the newest addition to the set, moves outside academia into competitive collegiate swimming and diving. The Instant #1 New York Times Bestseller! A competitive diver and an ace swimmer jump into forbidden waters in this steamy college romance from the New York Times bestselling author of The Love Hypothesis. Together, the five books share Hazelwood's signature ingredients: intelligent, socially awkward women, love interests who see past their armor, and settings soaked in real scientific detail. Themes of imposter syndrome, mentorship, and choosing yourself recur throughout, but each story stands complete on its own, so readers can start anywhere in the set. Fans of grumpy-sunshine pairings, found family among labmates, and ambition-respecting romance will find plenty to love.

About the Author
Ali Hazelwood is the pen name of a scientist-turned-novelist credited with popularizing the STEM romance genre in contemporary fiction. Ali Hazelwood is the nom de plume of a bestselling Italian author of academia-set romantic comedies, and her background in neuroscience research shows up throughout her books' laboratories, lecture halls, and conference rooms.
