Gone by Jonathan Kellerman

Missing acting students Dylan and Michaela are found in the remote mountains of Malibu, battered and terrified after a harrowing ordeal at the hands of a sadistic abductor. But forensic evidence soon exposes the incident as a hoax, and the kids are charged as criminals themselves.

After examining Michaela, psychologist Alex Delaware is certain that there’s more to this sordid psychodrama, and his instincts prove dead-on when she is savagely murdered. Casting their dragnet into the murkiest corners of L.A., Delaware and homicide cop Milo Sturgis unearth more questions than answers—and a host of eerily identical killings. What bizarre and brutal epidemic is infecting the city with terror, madness, and sudden, twisted death?
