Detroit-based homicide detective John Barnes has seen it all, literally. Thanks to a technologically advanced machine, detectives have access to the memories of the living, the dying, and the recently dead. But extracting victims' experiences first hand and personally reliving everything up to the final, brutal moments of their lives, the sights, the sounds, the scents, the pain, is also the punishment reserved for the criminals themselves. Barnes has had enough. Enough of the memories that aren't his. Enough of the horror. Enough of the voices inside his head that were never meant to take root...until a masked serial killer known as Calavera strikes a little too close to home. Now, with Calavera on the loose, Barnes is ready to reconnect, risking his life and his sanity. Because in the mind of this serial killer, there is one secret even Barnes has yet to see.
