When the Imperial prison barge Purge-temporary home to five hundred of the galaxy's most ruthless killers, Rebels, scoundrels, and thieves-breaks down in a distant part of space, its only hope appears to lie with a Star Destroyer found drifting and seemingly abandoned. But when a boarding party from the Purge is sent to scavenge for parts, only half of them come back-bringing with them a horrific disease so lethal that within hours, nearly all aboard the Purge die in ways too hideous to imagine.

And death is only the beginning.

The Purge's half-dozen survivors will do whatever it takes to stay alive. But nothing can prepare them for what lies waiting aboard the Star Destroyer. For the dead are rising: soulless, unstoppable, and unspeakably hungry.
