Zodiac: The Eco-Thriller

Stephenson's (The Big U) improbable hero is Sangamon Taylor, a high-tech jack-of-all-trades who inhales nitrous oxide for kicks and scouts environmental hazards for GEE, the Group of Environmental Extremists. Taylor particularly wants to nab the polluters of Boston Harbor, whose toxic sludge he monitors by zipping from illegal pipeline to illegal pipeline in his inflatable Zodiac raft. His work is slow-going and boring until the concentration of deadly PCBs rises inexplicably and then mysteriously drops to nothing. And then the ""eco-thriller'' begins: the bad guys are everywhere as Taylor ferrets out the connections between his bizarre landlord, a nerdy friend from college who's at work on a top-secret genetic-engineering project for a high-tech company, an industrialist-turned-Presidential-candidate and the crazed fans of Poyzen Boyzen, a heavy-metal band. In creating this all-too-conceivable story of industry and science running amok, Stephenson puts his technological knowledge elegantly to use, but never lets gadgets and gizmos take over the story. The characters are entertaining, if broadly drawn, and the rip-roaring conclusion will make a dandy denouement in the movie rendition. Film rights to Warner Brothers. (May)
