York Times bestselling author of The Wicked Bargain and Most Ardently comes a high-stakes race to defeat a curse designed to kill--about a teen demon who wants to be human, a boy cursed to die young, and the murderous island destined to bury them both.

Dami is a demon determined to cancel every deal they've ever made in order to tether their soul to earth and become human again. There's just one person standing in their way: Silas. An irresistibly (and stubborn) cute boy cursed to die young, except for the deal with Dami that is keeping him alive. If they cancel the deal, Silas is dead. Unless... they can destroy the curse that has plagued Silas's family for generations. But to do so, Dami and Silas are going to have to work together. That is, if the curse doesn't kill them first. . . .
