Haunted by the ghosts of a missing persons case that turned his life upside down, Miller Brinkman is doing everything in his power to escape the past. He's exchanged his small-town digs for the big city of Boston, and his career as a private detective for the solitary life of a writer. One problem: his debut novel was a flop, and his savings are rapidly dwindling. To make ends meet, Miller begins consulting for the police, but what starts out as an easy paycheck leads him straight into the biggest case of his life-and a job with the F.B.I. As he crisscrosses the globe, working to solve a series of gruesome murders and put together a puzzle that grows more complex by the minute, Miller's past starts to catch up with him. Lucid dreams and unexplained visions have him questioning his own sanity, and a strange power is growing within him-but at what cost? When an old nemesis returns, it sends the F.B.I., a group of serial killers, and two ancient, bloodthirsty adversaries on a collision course. Can Miller and his team of agents stop the murders and prevent a war that would wipe humanity off the planet?
