The listing, Sphere by Michael Crichton has ended.
As in Crichton's Andromeda Strain (Knopf, 1969), the focus of this science adventure tale is humankind's encounter with an alien life form. Within a space ship lying on the sea bottom is a mysterious sphere that promises each of the main characters some personal reward: military might, professional prestige, power, understanding. Trapped underwater with the sphere, the humans confront eerie and increasingly dangerous threats after communication with the alien object has been achieved. The story is exciting and loaded with scientific and psychological speculations that add interest at no cost to the action, including an intriguing sequence in which human and computer attempt to decode the alien communication. As the story races to an end, suspicions of evil-doing fall as many ways as in a detective novel.
