Seven souls that must be saved. Fallen Angel Jim Heron has completed his first task: helping Vin Di Pietro to redeem his soul. Now he must identify and battle a demon that can take any form. Worse still, his old boss Matthias wants him to assassinate Isaac, a member of The Firm who's gone AWOL - and Jim's pretty sure he's supposed to save him.
