Criminal Macabre: Cell Block 666 — Steve Niles

Cal McDonald faces his greatest challenge yet - hard time! Framed in the death of a cop, Cal finds himself at the mercy of a sadistic and corrupt police force. But now, in some of the bleakest moments of his life, the things that make him different from the rest of the world might be the only things capable of keeping his sorry butt out of deeper trouble. Because it turns out that the things that would make most people want to give up and die - the strange, inhuman voices coming from adjacent cells, the mysterious visitors, the unlikely saviors in demonic disguise - are the things that have kept Cal alive long enough to see a way out. And just when Cal begins to unravel the conspiracy behind his own downfall, he uncovers a nightmare world of murder and corruption at the prison that has dozens of former prisoners turning in their graves - and clawing their way out!
