Fallen tells the story of a recently adopted teenage orphan, Aaron, and his search for his identity. On Aaron’s 18th birthday he learns from Camael that he is the Redeemer of the “Fallen”, angels who were discharged out of heaven during the war with hell.

The Redeemer is said to be able to give forgiveness to the Fallen for their sins so they can rejoin the Host. Camael is also there to protect Aaron from The Powers, those angels who hunt down the children of the Fallen in hopes of redeeming themselves.

Now Aaron must deal with his newfound supernatural talents and Verchiel (Lisa Lackey), the head of the Powers who is out to destroy him.
