Jill Marie Landis was born on November 8, 1948 in Clinton, Indiana, but moved to California when she was only ten years old. While studying for her B.A. in history from Long Beach State University, Landis held summer jobs working as a ride operator for Fantasyland at Disneyland.
Upon graduation, she spent ten years as a kindergarten teacher and then three years teaching English as a Second Language part-time. Although Landis wrote her first romance novel in junior high, she did not decide to pursue a writing career until 1983. Three years after she committed to writing a full-length novel, Landis sold a manuscript. From 1988 through 2003, she published sixteen historical romance novels. In July 2003, she made her debut in the contemporary romance genre. In 2008, her first inspirational historical romance, Homecoming, was published by Steeple Hill. It was followed in 2009 by The Accidental Lawman. Writing for Zondervan, Landis published Heart of Stone, the first book of the Irish Angels Series in 2010.
Landis and her husband of over thirty years, Steve, an actor and slack key guitar player, claim to share their eighty-year-old home in Long Beach, California, with the ghost of writer Upton Sinclair. The childless couple (by choice) also have a home in Hawaii where they now live full time.
Landis has successfully completed the 6.5 hour kayaking trip around Kauai's Na Pali coastline, and she also enjoys raising orchids, playing the ukelele, quilting and dancing hula.
