The reviver

"Revivers: people who are able to wake the recently dead and let them bear witness to their own demise... Twelve years after the first reviver came to light, they have been accepted by an uneasy public. The testimony of the dead is permitted in courtrooms across the world, and forensic revival is now a routine part of police investigation. Despite his troubled past, Jonah Miller is one of the best revivers in the US. But while questioning the victim of a brutal murder, he encounters a terrifying presence. Something is watching. Waiting. His superiors tell him it was all in his mind, a product of stress. Jonah is not so certain. Then the first journalist who brought revival to the public's attention is murdered, and Jonah is propelled into the hunt for answers."--Publisher description.
