Twelve bones are missing.
 
When a U.S. colonel is found murdered in his Istanbul home, the grisliest detail is the one that links his murder to another that soon follows. To Special Agent Vin Cooper, it looks like there’s a serial killer at large in Turkey.
But looks can be deceiving.

Onetime lovers, now the uneasiest of partners, Vin Cooper and Special Agent Anna Masters follow a trail of clues from Istanbul to Iraq and beyond. The victims were not selected at random. What looked like ritual was rife with clues. As evidence of a conspiracy snakes up the chain of command, these two seasoned special agents must dodge bullets, defuse bombs, and avoid being buried alive in their desperate effort to short-circuit a plan for world domination more audacious than they could ever have imagined.
