From Publishers Weekly
Weaving an epic of complex dimensions, Brin ( Startide Rising ) plaits initially divergent story lines, all set in the year 2038, into an outstandingly satisfying novel. At the center is a type of mystery: after a failed murder attempt, a group of people try to save the victim, recover the murder weapon, identify the guilty party and fend off other assassins, all the while being led through n + 1 plot twists--each with a sense of overhanging doom, because the intended victim is Gaea, Earth herself. The struggle to save the planet gives Brin the occasion to recap recent global events: a world war fought to wrest all caches of secret information from the grip of an elite few; a series of ecological disasters brought about by environmental abuse; and the effects of a universal interactive data network on beginning to turn the world into a true global village. Fully dimensional and engaging characters with plausible motivations bring drama to these scenarios. Brin's exciting prose style will probably make this a Hugo nominee, and will certainly keep readers turning pages. Copyright 1990 Reed Business Information, Inc.


From School Library Journal
YA-- Brin uses the escape of a manmade black hole that is eating away at the Earth's core and a plausible future of sophisticated, instant universal and global computer data linkage and retrieval to reexamine, explore, and expand upon the themes regarding genetic creation and advancement begun in Star tide Rising (1983) and The Uplift War (1987, both Bantam). There is an element of suspense and intrigue as the characters scramble to define, find, and solve the black hole damage before each other and before it's too late. Although less engaging than the previously mentioned books, this is timely in its investigation of current ecological issues and includes a welcome annotated bibliography and list of environmental organizations and addresses. --Joan Lewis Reynolds, West Potomac High School, VACopyright 1990 Reed Business Information, Inc.
