In the urban Boston ghetto known as the Weird, bad things go down. When one of the Dead is found decapitated, Conner is called in to consult. Even a dead Dead gets an investigation. Conner quickly finds himself in the middle of a political struggle between the humans and the fey that threatens to rock the city. As friends and foes line up, Conner has some difficult choices to make about who to trust and what must be sacrificed for a greater good.

The Conner Grey books get more complicated the further you get into them. Events from the first three books spill over into this one and you may want to go back and skim before you start UNPERFECT SOULS. Conner Grey's world is expanding with each book. More characters, more to keep track of. This remains one of the most intriguing series on the urban fantasy market. The black mass in Conner's head is finally getting some explanation, as is a conflict with a fairly major character that has been running through the story arc.
