The Corpse War is over. Or at least Will Ritter thought the war was over.
But Will quickly changes his mind when he is led through a doorway in time and finds himself in a future where the Earth has been all but destroyed. The Corpses, alien invaders who wear the dead like suits of clothing, have returned in horrific numbers.
In the wake of their destructive onslaught, a rag-tag group of survivors with some of Will's now grownup friends among them is all that's left of mankind. Will must take part in a desperate, last ditch effort to rewrite history, prevent the Second Corpse War from ever happening, and defeat this evil that has consumed mankind once and for all.
But victory, if such a thing is even possible, carries a heavy cost.
