Madison is dead, but not. She was killed by a dark reaper, but when he killed her, she took the amulet that gave him power. That amulet gives her a body. The light reaper who was suppose to protect her got there too late, so his punishment is to train her how to use the amulet.
And the training is not going well. Madison is recognized by another dark reaper and Barabas (her light reaper) must figure out what's going on. Madison isn't going to wait for him, though. While he's asking the powers that be, she's become a target for the dark reapers. She has to learn how to save herself and those she cares about.
An interesting twist on the fallen angel idea. Lots of excitement, little to no romance, and lots of humor. The amount of people in the book can be daunting, but still makes sense.
