Born in 1944, Glen Cook grew up in northern California, served in the U.S. Navy, attended the University of Missouri, and was one of the earliest graduates of the well-known "Clarion" workshop SF writers. Since 1971 he has published a large number of SF and fantasy novels, including the "Dread Empire" series, the occult-detective "Garrett" novels, and the very popular "Black Company" sequence that began with the publication of The Black Company in 1984. Among his SF novels is A Passage at Arms.
After working many years for General Motors, Cook now writes full-time. He lives near St. Louis, Missouri, with his wife Carol.
