Below Zero
It will take the frosty terrain of the Arctic to show these rival scientists that their chemistry burns hot.
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…
Hannah’s got a bad feeling about this. Not only has the NASA aerospace engineer found herself injured and stranded at a remote Arctic research station—but the one person willing to undertake the hazardous rescue mission is her longtime rival.
Ian has been many things to Hannah: the villain who tried to veto her expedition and ruin her career, the man who stars in her most deliciously lurid dreams…but he’s never played the hero. So why is he risking everything to be here? And why does his presence seem just as dangerous to her heart as the coming snowstorm?
To read Mara and Sadie’s stories look for the novellas Under One Roof and Stuck with You available now from Berkley!

Ali Hazelwood
Before she ever dreamed of bestselling romance novels, Ali Hazelwood was elbow-deep in peer-reviewed journals, writing about brain stimulation and cognitive neuroscience—fields where swoony glances and happy endings were, unfortunately, in short supply. But somewhere between lectures, lab work, and grading papers, she found herself craving a different kind of narrative. One with emotional tension, sharp banter, and the thrill of two people realizing they’re absolutely doomed to fall for each other.
