Kathleen Ann Goonan's first novel is an impressive sci-fi debut, combining the themes of post-holocaust America and rampant nanotechnology. This imagined technology of molecule-sized machines and computers has excited many science fiction writers with its possibilities for total control of matter, atom by atom--including human flesh and DNA. In Goonan's future America, cities brought to life with nanotechnology or "nan" have mutated in strange, threatening ways. Rural areas, meanwhile, were devastated by nan-based plagues. Our heroine Verity, raised by a rustic Shaker community that rejects most technology, feels a mysterious compulsion towards learning machines and the closest transformed city. This is Cincinnati, whose skyscrapers have blossomed into exotic nan flowers between which huge artificial bees carry pollinating information. Verity's adventures there are complex, flickering between real-life action, virtual reality and chemically induced all-senses hallucinations. Eventually--the old, old sci-fi story--Verity realises that she herself was created to redeem the malfunctioning city. Its inhabitants are trapped in pleasant but futile cycles of dreams and play-acting (living the roles of Hemingway, Gertrude Stein and others): Verity must somehow free them. Well written and colourfully imagined, the story requires close attention to thread its maze of realities and unrealities. --David Langford
