Probability Sun

May 21, 2001
Human beings (aka Terrans) have a brighter future in this fairly standard space adventure than they did in Kress's Probability Moon
(2000), which introduced the enemy Fallers, friendly Worlders and space tunnels left behind by a long-lost alien race. In the previous book, Worlders pushed humans off their planet because they didn't "share reality." Now the Terrans come back to try to retrieve the Worlders' "artifact," a machine that generates a probability field and holds the key to human survival in the fight against the Fallers. The action moves from colonies on the moon and Mars, to a military space ship, the Alan B. Shepard, to World, a planet at a great distance from Earth that's inhabited by a harmonious alien race of total empaths. The author grounds her morally complex plot in the physics of probability. As usual with Kress, her eccentric characters add depth. Major Lyle Kaufman, a military leader who dislikes leadership; Tom Capelo, a brilliant, antisocial physicist still grieving for a dead wife; and Ann Sikorski, a xenobiologist who questions their right to take the artifact, all struggle with their roles. In addition, female Worlder Enli must work with humans and with her own kind to create a compromise. Readers will start this novel because of Kress's reputation, will read it for the adventure and will like it for the characters and the science. (July 18)FYI:Kress's husband is SF writer Charles Sheffield.

The immediate sequel to " Probability Moon" (2000) continues humanity's war against the alien Fallers, a war humanity is losing. It again shows scientists and the military at odds if not in outright conflict while portraying the strengths and limitations of both with admirable even-handedness. A shipload of scientists has come to study the alien artifact discovered on the planet World, and the ship's military crew is holding the only Faller POW as a secret captive. The questions that permeate the tightly paced story are whether scientists and the military can cooperate to learn the nature of the artifact--scientific storehouse or doomsday machine--and whether either of those parties will procure the cooperation of the captive Faller, whose perception of reality is unfathomably different from that of any of the humans. Displaying a typically strong synthesis of Kress' many gifts, the novel leaves the door wide open for at least one successor.(Reprinted with permission of Booklist, copyright 2001, American Library Association.)
