The Nephilim, a mystic and ancient order, will go to any length to protect their mysteries and the greatest secret of all-the very knowledge of their existence. Ty Roland, stuck in an unsatisfying and routine job, spends his life avoiding responsibility. Life changes suddenly for Ty when his estranged grandfather dies, leaving him and a forgotten cousin Debbie, an unlikely inheritance-and a mysterious note with a cryptic code they must decipher. As they unravel the mysteries of their grandfather's past, a bazaar world of knowledge, power, and deceit threatens everything they believed to be true while bringing Ty and Debbie dangerously close to the shadowy secrets of the Nephilim.
