Deep in the Alaskan wilderness, a mummified body is discovered in the ice, the victim of a bizarre ritualistic killing that happened nearly six thousand years ago. For journalist Maura County, this story is her ticket to the big time -- if she can get the help of the FBI's top profiler.

Special Agent Ulysses Grove is the best of the best -- a born manhunter. He's also a man on the edge, haunted by both personal tragedy and a recent spate of horrific, unsolved homicides. Now, in a remote lab, he's about to make a shocking discovery. Everything about the prehistoric murderer -- signature, M.O., the tiniest of details -- matches up to the serial killer who has eluded Grove for months.

As past and present collide, County and Grove are plunged into a nightmare journey that will take them into the darkest reaches of the human heart as they try to stop a cycle of evil as eternal and powerful as time itself...
