Undeath is a manageable condition. That's what the media says, anyway: with the help of the miracle life-extension drug, Lazarus, the Undead can retain their humanity and live normal, happy lives. Without it, they become violent, mindless walking corpses. Davin Montoya was eager to believe all of that. Forced to drop out of college to take care of his teenage sister, Zoe, after their father drank himself to death, he was more than happy to sign the no-good alcoholic over to the government's Lazarus House for treatment. That was one less thing for him to worry about. Until an accident left him joining the ranks of the freshly deceased himself. Now, keeping his death a secret is the only way to keep his sister out of foster care. But to do so, he must venture into the underground society of Unregistered Undead - a dangerous world of drug deals and government resistance. But when their access to Lazarus begins to run dry, the truth starts to unravel...and it's not what anyone expected.
