What good are angels?

Fallen from heaven's grace, the angel Cassiel finds herself in an impossible situation: accused of murder and racing against time to rescue a young elven girl from the clutches of darkness. In the face of this horror, she wrestles demons both inside and out.

Alongside her stand her friends: Jim, a disabled human combat veteran; Dust, an orc who serves in the church kitchen; and Eirlas, an elven former gangbanger. Can they save the girl and stop the demons in time while the city of Boston hangs in the balance?
