Edward M. Lerner worked in high tech for thirty years, as everything from engineer to senior vice president, for much of that time writing science fiction as a hobby. Since 2004 he has written full-time, and his books run the gamut from technothrillers, like Small Miracles, to traditional SF, like his InterstellarNet series, to, with Larry Niven, the grand space epic Fleet of Worlds series of Ringworld companion novels.   Ed’s short fiction has appeared in anthologies, collections, and many of the usual science fiction magazines. He also writes the occasional nonfiction article, on topics as varied as asteroid deflection, privacy (or lack thereof) in the Internet age, and the role of communications in SF.
