Two teens in love must make the ultimate sacrifice to avert global disaster... First-period English class is the last place 17-year-old Laena expects to have her entire existence thrown into a tailspin. But when Cree, a jaw-droppingly gorgeous boy, mysteriously appears in her classroom, Laena knows nothing will ever be the same. Before Laena can decide who Cree really is or whether anything he says is true, she falls for him. Hard. Cree claims he has seen the future, and it is devastating. Working frantically to avert impending disaster, the two teens plunge into a battle between science and faith that threatens everything Laena has ever known. Surviving high school is tough. But it's even tougher while fighting for your life, the boy you love, and the fate of the planet.
