In a world devastated by a mutating alien life form, Ava wakes from decades of cold sleep with no memory of her past—only the knowledge that her very existence is both a weapon and a curse. Her blood is toxic to the creatures hunting humanity, but controlling the monstrous power within her might be impossible.

Gabriel, a rescue squad member haunted by loss, discovers Ava during a mission. Torn between fear and hope, he must decide if she's humanity's last chance at survival or its greatest threat. As the alien menace spreads and Ava's powers spiral out of control, the line between savior and destroyer blurs.

Can Ava and Gabriel trust each other enough to face the darkness—both outside and within?
