What They're Saying

Critics Review

Contemporary romance’s unicorn: the elusive marriage of deeply brainy and delightfully escapist…The Love Hypothesis has wild commercial appeal but the quieter secret is that there is a specific audience, made up of all of the Olives in the world, who have deeply, ardently waited for this exact book.


Funny, sexy and smart.


This tackles one of my favorite tropes - Grumpy meets Sunshine - in a fun and utterly endearing way… I loved the nods towards fandom and romance novels, and I couldn’t put it down. Highly recommended!


Pure slow-burning gold with lots of chemistry.

* Popsugar *

A beautifully written romantic comedy with a heroine you will instantly fall in love with, The Love Hypothesis is destined to earn a place on your keeper shelf.


Smart, witty dialogue and a diverse cast of likeable secondary characters… A realistic, amusing novel that readers won’t be able to put down. * Library Journal, starred review *
With whip-smart and endearing characters, snappy prose, and a quirky take on a favourite trope, Hazelwood convincingly navigates the fraught shoals of academia… This smart, sexy contemporary should delight a wide swathe of romance lovers. * Publishers Weekly *

When a book has a certain type of magic between the pages, you manage to get from the prologue to the epilogue without coming up for air … The Love Hypothesis was one of these books.

I fell in love with Adam’s and Olive’s relationship … it’s the best romance book I’ve read this year * Birmingham Live *

About The Author

Ali Hazelwood

Ali Hazelwood is the New York Times and Sunday Times bestselling author of multiple romance novels, as well as a writer of peer-reviewed articles about brain science, in which no one makes out and the ever after is not always happy. Originally from Italy, she lived in Germany and Japan before moving to the US to pursue a PhD in neuroscience. When Ali is not at work, she can be found crocheting, eating cake pops, or watching sci-fi movies with her three feline overlords (and her slightly-less-feline husband).
