From New York Times bestselling author James Rollins comes a stirring story of a soldier and his military war dog who are drawn into a dark mystery tracing back to World War II and a lost treasure tied to the bones of the dead.

Off the streets in the medieval heart of Budapest, Captain Tucker Wayne and his war dog, Kane, rescue a mysterious woman fleeing three armed men. The secret she holds will unlock a terrible treasure, one steeped in blood and treachery, tied to a crime going back to the fall of Nazi Germany and a heritage of suffering and pain that reaches out from the past to wreak havoc today. In a final showdown in the depths of a lost cemetery, truths will be unearthed, treasures exposed, and the fate of all will rest upon the shoulders of one man and a dog whose courage is beyond measure.

Included with this thrilling story is sneak peek at Bloodline, where the further exploits of Tucker and Kane will be revealed.

"Former Army Ranger Tucker and his amazing dog Kane make for absolutely riveting reading in this page-turner of a genetic mystery. James Rollins really outdid himself this time. Readers get to experience what it's like to walk in the paws of a super highly trained military dog, and the deep bond between military dog and handler. I look forward to more James Rollins books with this intrepid pair. Four paws up!"
