Description:

Greg Egan became the hottest new science-fiction author of the 1990s and won the Hugo and John W. Campbell Memorial awards by extrapolating cutting-edge quantum physics and consciousness theory to create rigorous and radical new visions of the posthuman future. Schild's Ladder affirms Mr. Egan's place, with Olaf Stapledon and Poul Anderson, among the giants of cosmic-scale SF. In Schild's Ladder, humanity has transcended both death and Earth, and discovered its home world is nearly unique as a cradle of life. As it spreads throughout the galaxy, humanity enjoys an almost utopian existence--until a scientist accidentally creates an impenetrable, steadily expanding vacuum that devours star systems and threatens the entire universe with destruction. Tchicaya is a Yielder, member of the faction that believes this "novo-vacuum" deserves study. The opposing Preservationists--among them Mariama, his first love--seek to save worlds and destroy the novo-vacuum. Discord heats to terrorist violence; then enmities and alliances are turned upside-down by a discovery that may mean the novo-vacuum is, instead, a new and very different universe--and one which may contain life. --Cynthia Ward

SUMMARY:
Twenty thousand years into the future, an experiment in quantum physics has had a catastrophic result, creating an enormous, rapidly expanding vacuum that devours everything it comes in contact with.Now humans must confront this deadly expansion. Tchicaya, aboard a starship trawling the border of the vacuum, has allied himself with the Yielders -- those determined to study the vacuum while allowing it to grow unchecked. But when his fiery first love, Mariama, reenters his life on the side of the Preservationists -- those working to halt and destroy the vacuum -- Tchicaya finds himself struggling with an inner turmoil he has known since childhood.However, in the center of the vacuum, something is developing that neither Tchicaya and the Yielders nor Mariama and the Preservationists could ever have imagined possible: life.
