Nyle doesn't want to be there. But something is very wrong in the District of Portland, and the cold call of death forces his arrival. If he can't lay the dead fast enough, his long life, begun in Anglo-Saxon England, will end.
Portland's electronic walls do more than keep the mutants out. The government is using them to block Nyle and his kind, the ravens, who roam the world, freeing the dead from their bodies where they remain trapped till a raven's arrival.
Cait, a Portlander working as a beautician, has her own troubles, dodging the GM (genetic modification) police and struggling with rent. But the dead are invading her dreams. Nyle tells Cait that she's not genetically modified. She's a necromancer.
In the District of Portland, the dead are being trapped indefinitely and used as energy sources. Nyle and Cait must stop the technology from spreading before the abuse of the dead becomes a worldwide menace and they themselves end up on a laboratory table or trapped in a machine.
