Kathy Tyers (born July 21, 1952) is an American author and musician currently living in Bozeman, Montana.
Kathy Tyers Gillin (née Moore) was born and raised in Long Beach, California. She obtained a degree in microbiology from Montana State University, where she met her first husband Mark Tyers. After their marriage, she returned to school and became certified to teach grades K-12. When their church opened a private school, she took over teaching the lower grades. In 1979, she retired from teaching to start a family; her son Matthew was born in 1981 and she began writing in earnest two years later.
Tyers sold her first novel Firebird to Bantam Spectra in 1986. She subsequently sold Fusion Fire (1988; a sequel to Firebird), Crystal Witness (1989) and Shivering World (1991). During this period she also authored a nonfiction travel book and, with her husband, released two CDs of folk music, Leave Her, Johnny and The Very Best Dreams on which she played flute and Irish harp. In 1991, while working on another speculative fiction novel, she was approached with an opportunity to write a novel in the Star Wars Expanded Universe. Her novel The Truce at Bakura (1993) reached the New York Times bestseller list.
Despite her success, after the sale of her novel One Mind's Eye, Tyers took a complete sabbatical from writing from 1994 to 1997. She eventually returned to writing, specifically targeting the Christian Booksellers Association in an attempt to sell Christian science fiction, and Bethany House Publishers published rewritten versions of Firebird and Fusion Fire.
