Kathleen Kelly was born on 14 July 1947 in the Central Valley of California, USA. She obtained a degree in Anthropology and History from the University of California in Santa Barbara. She was a real estate broker, when she met her future husband, Larry Jay Martin. A short time after the two became acquainted, Larry asked her to read an unpublished manuscript of an historical western he'd written. Kat fell in love with both the book and the author! Then, after doing some editing for him, she thought she'd try her own hand at writing. She moved on to become a full time writer.

The New York Times bestselling writer, among her many awards, has won the prestigious RT Book Review Magazine Career Achievement Award. To date, Kat has over eleven million copies of her books in print.
