Trust has begun to break down in Heaven in this fourth volume about a young human girl trying to make her way through devil school. A senior angel is imprisoned on suspicion of stealing a sacred heirloom from a church. But when his cell explodes and there’s no sign of him, further suspicions – that he’s in league with the underworld – start to bubble to the surface. Could it be enough to spark off a full on war between Heaven and Hell? And what will become of Pam, who only wants to become a devil because someone told her it was her only route back to becoming human again?
