When the cosmic fabric separating the dimensions rips open and spits the inhabitants of Purgatory into the small, west texas town of Eden, the initial rip is so forceful it kills everyone and everything that isn't underground. The only thing that saves 14-year-old Jack is that he just happened to be in the school basement at the time. an unwilling leader, Jack finds himself forced to perform tasks he never would have imagined before the rip. But with the help of a motley crew of survivors, including a deaf dog named Snake - and odd brain-blasts of classic rock-n-roll - Jack grows into the guy who can make decisions that just might save humanity from annihilation.
