"One way or another the dues of the past must be paid."

Mysterious forces are driving a deadly wedge between Riley and his best friend, a fallen angel named Jonathan.

A year ago, Riley had come to put his trust and his very life in Jonathan's hands, but something is happening to Jonathan, something very dark, and it's putting Riley at risk. He was once Reiley's most trusted friend, but now Riley is beginning to fear him, and for good reason.

They will both face impossible decisions, which means only one of them will survive as the forces of evil once again come after them.
