Invader

The laws of robotics

1. A robot may not injure a human being, or through inaction, allow a human being to come to harm.

2. A robot must obey the orders given it by human beings, except where such orders would conflict with the First Law.

3. A robot must protect its own existence, as long as such protection does not conflict with the First or Second Law.

This novel is dedicated to the memory of my maternal grandmother,

Mae Franking,

Who passed her English and Scottish descent to me and became the first novelist in the family.

Special thanks are due during the time of writing this novel to Dr. William Q. Wu and Cecile F. Wu, my parents, for indulging my lifelong interest in history; Riucia Mainhardt; Bridgett and Marty Marquardt; Michael D. Toman; and John Betancourt, Leigh Grossman, Keith R. A. DeCandido, and Byron Preiss.
