Piper Crell has had a hard start on her life. Both her parents died, the safe house is falling apart, and most of all, God seems far away. No matter what she seems to do, something bad greets her around every corner.

But just recently, they've been getting more attacks against the safe house. Cravers, they call them. Insane humans who've been infected by this virus spreading across the whole United States and some parts of the outside world.

But Piper isn't afraid of death. If she dies, so what? But her friends drag her on some crazy journey to start their very own safe house. A Christian safe house, that is. Since the other one kicked out Christianity altogether, Piper and her friends take on the Cravers and go on their way. But it doesn't go as planned. They run into many obstacles along the way. Way more than expected. They gain some friends and lose some.

Will Piper and her friends all survive? Will someone try and stop them?
