A USA Today Bestseller!

From the New York Times bestselling author of The Love Hypothesis comes a new steamy, STEMinist novella…

A scientist should never cohabitate with her annoyingly hot nemesis—it leads to combustion.


Mara, Sadie, and Hannah are friends first, scientists always. Though their fields of study might take them to different corners of the world, they can all agree on this universal truth: when it comes to love and science, opposites attract and rivals make you burn…
 
As an environmental engineer, Mara knows all about the delicate nature of ecosystems. They require balance. And leaving the thermostat alone. And not stealing someone else’s food. And other rules Liam, her detestable big-oil lawyer of a roommate, knows nothing about. Okay, sure, technically she’s the interloper. Liam was already entrenched in his aunt’s house like some glowering grumpy giant when Mara moved in, with his big muscles and kissable mouth just sitting there on the couch tempting respectable scientists to the dark side…but Helena was her mentor and Mara’s not about to move out and give up her inheritance without a fight.
 
The problem is, living with someone means getting to know them. And the more Mara finds out about Liam, the harder it is to loathe him…and the easier it is to love him.
 
To read Sadie and Hannah’s stories look for the novellas Stuck with You and Below Zero, coming soon from Berkley!
Praise for The Love Hypothesis

"A literary breakthrough…The Love Hypothesis is a self-assured debut, and we hypothesize it's just the first bit of greatness we'll see from an author who somehow has the audacity to be both an academic powerhouse and divinely talented novelist."—Entertainment Weekly

Contemporary romance's unicorn: the elusive marriage of deeply brainy and delightfully escapist.”—Christina Lauren, New York Times bestselling author

“Funny, sexy and smart, Ali Hazelwood did a terrific job with The Love Hypothesis.”—Mariana Zapata, New York Times bestselling author

“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!”—Jessica Clare, New York Times bestselling author

"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."—Elizabeth Everett, author of A Lady's Formula for Love

"Smart, witty dialog and a diverse cast of likable secondary characters...A realistic, amusing novel that readers won’t be able to put down."—Library Journal, starred review

Ali Hazelwood is the #1 New York Times bestselling author of Love, Theoretically and The Love Hypothesis, 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 running, eating cake pops, or watching sci-fi movies with her three feline overlords (and her slightly-less-feline husband). View titles by Ali Hazelwood
