Marla Mason, guardian mage of the east coast city of Felport, returns in her second major magical challenge (after Blood Engines): catching a psycho, and psychic, dream “reweaver” before the psycho turns into an endless nightmare. Genevieve Kelley, a former apprentice sorcerer, vanishes from the Blackwing Institute for Criminally Insane Sorcerers after laying catatonic for 15 years, having put herself into a protective deep sleep after being raped. With the ability to “reweave” physical reality, the terrified psychic is trying to escape Reave, king of nightmares, the avatar of her rapist. Marla, drawn in and out of Genevieve's dream reality, hires Ted, a former street bum turned skeptical personal assistant, and Joshua, a delectable “lovetalker,” to help her put a lid on Genevieve as an important sorcerer assembly approaches. A rival sorcerer, Gregor, also seeks to eliminate the marvelous Marla by hiring Zealand, a “slow assassin.” Pratt keeps the action lively in this wonderfully whimsical urban fantasy as the adventure of Genevieve takes some wonderfully imaginative twists and turns.
