Before Zero by Ali Hazelwood

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?
