Time and Again by Clifford Simak (1983, Paperback) In Time and Again, Mankind is spread thin across the stars and to help hold the frontier he has created biological androids. Created in the lab by chemical means, androids are sterile and cannot reproduce but in all other respects are as human as their creators. None the less, androids are treated as property and bear a mark on their foreheads to distinguish them from "true" humans. Androids dream of one day being acknowledged and treated as the equals of the "humans" and Asher's idea is the key for which they have been searching. Asher soon becomes the center of a struggle between three groups; humans of the present who fear any new idea that might loosen Mankind's tenuous grip on the stars, humans of the future who, via time travel, are waging a quiet war to alter the past to maintain the current status quo, and the androids of the future who struggle to let Asher's idea be born. Simak weaves these disparate elements into a delicious story. Book measures approximately 8? x 5oe?, with 225 numbered pages. NOT price clipped, NOT Ex-Lib.
