Why I love it

Rachael Burlette
BOTM Editorial Team

What is the formula for a perfect romance? For me, it’s about the sweet moments, the witty banter, and amazing chemistry. I’m particularly drawn to love stories that also go beyond falling in love, which is why I was excited to read about Olive’s journey as a young scientist. I loved her drive and ambition. Once I began reading The Love Hypothesis, I knew that it had all the right elements to become one of my new favorite romances.

Set in the world of academia, Olive is a Ph.D. biology student who spends most of her time in a lab. She certainly doesn’t have time for dating. So when she kisses a random person at her university to convince her best friend, Anh, that she is doing just fine, she finds herself entering into a fake dating agreement with the infamously grumpy Professor Carlsen. It’s the perfect plan: Olive’s friends will stop worrying about her and Adam’s bosses will believe he’s not leaving for a new job anytime soon. Adam and Olive just need to follow a few ground rules and not fall in love. What could possibly go wrong?

On the surface, this book is a fun romance about a hilarious fake dating scheme. But it’s also more than that. It’s a glimpse into the world of academia and the obstacles women face in the male-dominated STEM field. I found myself reading this book whenever I had the chance. I felt completely invested in Adam and Olive’s love story and how everything would unfold. The Love Hypothesis is everything that you’ll want in your next read. I have a theory you’ll love this book—I know I did!

As a third-year Ph.D. candidate, Olive Smith doesn't believe in lasting romantic relationships—but her best friend does, and that's what got her into this situation. Convincing Anh that Olive is dating and well on her way to a happily ever after was always going to take more than hand-wavy Jedi mind tricks: Scientists require proof. So, like any self-respecting biologist, Olive panics and kisses the first man she sees.

That man is none other than Adam Carlsen, a young hotshot professor—and well-known ass. Which is why Olive is positively floored when Stanford's reigning lab tyrant agrees to keep her charade a secret and be her fake boyfriend. But when a big science conference goes haywire, putting Olive's career on the Bunsen burner, Adam surprises her again with his unyielding support and even more unyielding... six-pack abs.

Suddenly their little experiment feels dangerously close to combustion. And Olive discovers that the only thing more complicated than a hypothesis on love is putting her own heart under the microscope.

  • New Braunfels, TX

    LOVED. I was immediately drawn into the story, and I loved the characters’ acknowledgement of the romcom scenario. I’m so sad that it’s over—serious book hangover. Excited for more Ali Hazelwood!❤️❤️

  • Baltimore, MD

    So I’m not one to read rom coms, but this one completely stole my heart. I read it in one day, I just couldn’t put it down ???? I’m so sad it’s a debut and I can’t get more !!!! I need another Adam fix

  • White Bear Lake, MN

    The Love Hypothesis was everything to me! It gave me all the gooey romance feels, giggles, “aw” moments, with the banter and actions between Olive and Adam. If you don’t know me, I’m all about science

    Read it in 2 days! Loved every character, fake-dating romance, the SUNSCREEN, women in STEM…honestly had trouble sleeping because I wanted to know what would happen! My heart still hasn’t recovered ❤️

  • Metamora, IN

    I LOVED this book so much …I had to rush home from work today to finish it! I loved every minute of Adam and Olive’s love story, and I’m sad it’s over! I will be recommending this book to everyone!!

  • Keokuk, IA

    I liked the academia aspect and fake dating is always fun. There weren’t many surprises, one twist I didn’t see coming it was a pretty straight forward book. I loved the main character she was quirky.

  • Silvis, IL

    This book was great from the first page. I also received my PhD and academia can be hard- especially for women, which the author really brings to life. Even if you aren’t in academia it’s still great

  • Nampa, ID

    I finished this book in one day. Once I picked it up I could not put it down. It will keep a special place in my heart and on my forever shelf! If you’ve been contemplating this book here’s your sign!

  • Allentown, PA

    Uhhhhh!!! Didn’t even realize I stood up till 2:50am to finish this! I just couldn’t stop reading! Where can I find me an Adam?! I loved their sense of humor and back & forth banter! Just amazeballz!

  • Slatedale, PA

    After a coworker friend recommended it as a light addictive read, I had to dive in. It’s delightful. And the way Olive’s sexuality was depicted was so relatable to my own journey with my Ace identity.


    Couldn't put this down! Loved the combo of ladies kicking butt in STEM (we need more of this!) + adorable love story. Even tho the fake dating trope can be cheesy, this storyline was well written. ❤️

  • Canton, MI

    This book was so cute and I can’t wait to see more from this author! The plot was predictable but that’s okay for a light read. The main characters were so likable and had great chemistry together.

  • Waco, TX

    I LOVED this book and LOVED the characters! I read this book in a day and just couldn’t put it down. I usually don’t pick romance novels but this one was so fun, quirky and romantic I just loved it!

  • Madison, WI

    Literally devoured in 3 sittings, lost sleep to stay up late reading, babbling to everyone I know about it. It was a whole thing. My only complaint is that Kylo Ren is on the cover for some reason. ????

  • Richmond, TX

    I loved this book. Stayed up way too late for a few days and couldn’t read it fast enough. Loved the personalities of all the characters. The story never felt forced like some romantic stories tend to

  • Reno, NV

    Very strongly liked -almost loved- it! It still reads a lot like fan fiction, but that’s not a bad thing. The author clearly knows academia inside and out; plus, a little Reylo is never a bad thing.

  • Sparks, NV

    Absolutely loved the humor, chemistry and tension! Such a fun read that was playful and approached deeper topics. A stand out debut and an author I can’t wait to follow. This is a favorite of the year

  • Port Lavaca, TX

    LOVE LOVE LOVEEEE this Book!! I couldn’t put it down, when I had to, all I could think of was picking it back up! So cute, funny, happy, sad, sexy, all wrapped up in one amazing book! Recommend 100%!
