(Book)

Series numeration from goodreads.com

Sequel to: The unforgiven.

Playing the victim of a vampire king on an island off New Orleans is actress Avalon Morgan's creepiest role to date. Its also scary good fun-- until the victim of a real killer is discovered on set, laid out for all to see. With production shut down, Avalon can't stop thinking about the chilling crime scene, or Finley Stirling, the FBI agent working the case. With a rising body count and zero leads, Fin can't help but be impressed by Avalon's amateur sleuthing, which takes her to the darkest corners of the internet, where killers confess their crimes. One such account is a dead ringer for the murders, but when the evidence vanishes, nobody believes Avalon except for Fin. With no one they can trust, Avalon and Fin are determined to unbury the truth at any cost, but a return to the deadly island could be the last thing they do.
