Born and raised in San Francisco, Charles spent his boyhood summers wandering the hills, creeks and forests of northern California with his two best friends, sharing adventures that shaped some of the activities in Irish the Demon Slayer. After graduating from the University of California in Berkeley he joined the Bay Area technology explosion, a choice that helped him support and raise a family of six boys and three girls. With his family grown, he left Silicon Valley in 2001 to forge a career in creative writing. Charles and his wife enjoy life in Northern California.
