The gospel of Z

"In the ten years since zombies killed the world, Jory Gray has found exactly one person who matters. Her name is Linse. But when he wakes to find her gone, to join the church, his world falls apart all over again. Jory's suicide mission to save her will lead him deep into the restricted zone, into the bowels of the military, the underbelly of the church, and, worse, it will give him a glimpse into a past that's supposed to be ten years dead, a past still contained in a document that never should have existed: The Gospel of Z"--Page 4 of cover.
