A fast moving drama in Istanbul and at sea on the Mediterranean, with suspense and action on a luxury cruise ship and at ports from Istanbul to Rome. Finn Greer returns from combat in Afghanistan and finds his morals taxed in a dangerous assignment to Istanbul. Lured by an insurance reward, he is recruited to recover a lost historic ruby, a royal gem that harbors a curse hundreds of years old. Competing for control over the destiny of the bloodstone, Finn shields his covert role on an elite international force. The mission intensifies as he infiltrates a smuggling ring on a Mediterranean cruise to flush out the criminals and kingpin. A web of mistrust with double agents and Interpol keeps him on the run with Nicolle Colbert, and he'd do anything to save her.
