From About the Author in Bishop's Heir:

Katherine Kurtz was awarded a B.S. in chemistry from the University of Miami and attended medical school for a year before deciding she would rather write about medicine than practice it.  She earned an M.A. in medieval English history from UCLA while writing her first two novels, and worked as an instructional designer for the Los Angeles Police Academy for the next ten years.  She is also a professionally trained hypnotist, an avid horsewoman, and an avowed cat person.  She has a husband who wears kilts, a ten-year-old son named Cameron, a vintage Bentley motorcar once owned by HRH the Duke of Kent, and hopes soon to live in a castle in Ireland.  Besides the Deryni Trilogy, the Camber Trilogy, and several short stories set in the Deryni universe, she has recently published a World War II thriller, Lammas Night, dealing with magic worked to keep Hitler from invading England in the summer of 1940.  She is currently at work on the second and third books of the Histories of King Kelson, with at least two more trilogies planned.
