Summary of The Love Hypothesis by Ali Hazelwood

So, what’s The Love Hypothesis all about? Picture this: Olive Smith, a third-year Ph.D. candidate, is too busy juggling her research, teaching duties and trying to prove herself in the cutthroat world of science to worry about love. Enter a hilariously complicated situation where Olive, in an attempt to convince her best friend that she’s over an old flame, impulsively kisses the first guy she sees. That guy just so happens to be Dr. Adam Carlsen, a young and incredibly intimidating professor known for his brilliance. He’s also known for his cold, cutting critiques.

Surprisingly, Adam agrees to keep up the ruse and fake-date Olive for reasons of his own. What starts as a mutually beneficial arrangement slowly evolves into something more real than Olive ever anticipated. Cue the lab partners’ puns, academic banter and plenty of steamy (and awkward) moments. The question quickly becomes whether Olive can come to terms with her growing feelings for the professor. Despite his grumpy exterior, Dr. Carlsen seems to care for her more deeply than she could have imagined.

Review of The Love Hypothesis by Ali Hazelwood

Let me tell you—Ali Hazelwood knows how to craft a story that’s not only adorable but also clever. The Love Hypothesis is a rom-com that brings a new twist to the fake-dating trope. Set in the realm of STEM academia, it’s an arena often left unexplored in mainstream romance. What really makes this book a standout is how relatable and multifaceted Olive is as a protagonist. She’s ambitious, a little scatterbrained, fiercely independent and wonderfully flawed. Watching her navigate the highs and lows of academic life while wrestling with her unexpected attraction to Adam feels genuinely refreshing.

And speaking of Adam Carlsen, he’s the epitome of the broody but secretly kind love interest we all can’t help but adore. Some might argue that he falls into the “grumpy-sunshine” trope. However, Hazelwood gives him enough depth that he never feels like a cliché. His development throughout the story is what makes their relationship feel authentic. Particularly through moments that show his vulnerabilities and unwavering support for Olive.

Another reason this book shines is its humor. From Olive’s inner monologue to the perfectly timed academic jokes, Hazelwood strikes a balance that keeps things lighthearted without undercutting the emotional weight of the story. And let’s not forget the chemistry. The tension between Olive and Adam is palpable. Even the simplest gestures—like a shared glance or a brief touch—carry meaning. By the time you get to the more romantic scenes, you’re fully invested in their journey.


The story’s pacing deserves a shoutout. Hazelwood skillfully builds anticipation and keeps readers hooked from chapter to chapter. However, some may find that a few secondary characters feel a bit underdeveloped compared to Olive and Adam. But honestly, that’s a minor hiccup in an otherwise engaging tale.
