At age ten, Bill Jensen and his “imaginary” friend, Yasu, inadvertently unleash a devastating power that kills three schoolmates.
A decade later, Bill wrestles with making his way in the world while dealing with the inner turmoil of determining whether Yasu is devil or delusion. Still haunted by the confusing events of their childhood, Bill and Yasu struggle to recognize their extraordinary power and purpose.
Bill’s secret power mysteriously begins to attract the interest of bizarre creatures, including a bulimic "werewolf" and a man claiming to be an ancient soul-eating dragon. The power’s pull might also be contributing to Bill’s turbulent romance with an unstable witch, named Corina, and luring the attention of a psychotic serial killer.
New aspects of the power begin to manifest just in time to help Bill and Yasu deal with escalating threats, which send the companions spiraling toward an uncertain destiny-- heroic salvation or evil oblivion?
