[New York]: HarperPrism, [1995]. Octavo, cloth-backed boards. First edition. "In this beautifully realized science fantasy novel, the world runs on a powerful, dangerous, and very possibly magical energy source called plasm. One day Aiah, a minor government employee, is sent to discover the source of a plasm leak and winds up smack in the middle of a revolution. The political machinations here are extremely complex and the action unflagging, but what raises this novel far above the average are Williams's baroque, world-encompassing city and his enormously inventive use of plasm. The strong sequel is CITY ON FIRE (1996)." - Anatomy of Wonder (2004) II-1254. [Reference: Sargent, British and American Utopian Literature, 1986-2009].
