Kathy Tyers is an American science fiction author.^[1]

Tyers, born in Long Beach, California, is a microbiology graduate and a certified K-12 teacher. She began her writing career in the early 1980s, publishing her first novel, Firebird, in 1986. She continued to write successful science fiction novels, including The Truce at Bakura, which reached the New York Times bestseller list. After taking a sabbatical from writing, Tyers returned to the field, targeting the Christian Booksellers Association. The rewritten versions of Firebird and Fusion Fire, along with a third novel, Crown of Fire, were marketed as Christian fiction. Tyers continued to contribute to the Star Wars universe with additional novels and short stories. After her husband's death in 2004, she took another sabbatical, during which she worked on an autobiography and earned a Master of Christian Studies degree. The Firebird Saga was completed with two more novels, and Tyers remarried in 2014.

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 published her first novel, Firebird, with Bantam Spectra in 1986. She subsequently published 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.^[2]

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.

The rewritten versions, published in 1999 and 2000 along with a third novel, Crown of Fire, were much more spiritual in nature and, in most markets, were marketed as Christian fiction instead of science fiction. They were published as a single volume edition in 2004. During the same period, Tyers was approached for the Star Wars market again and authored another novel, Balance Point, in addition to short stories for four Star Wars anthologies. Shivering World was revised and re-released in early 2004.

Tyers' husband, Mark, died from alcoholism in 2004.^[3] She took another sabbatical from fiction writing, working with guitarist Christopher Parkening on his autobiography Grace Like a River. In 2006, she entered Regent College in Vancouver, British Columbia, and after earning a Master of Christian Studies degree, she lived in Bellingham, Washington for a year before returning to Montana.

The three Firebird novels were re-released in an annotated version by Marcher Lord Press in 2011, followed by two additional series novels: Wind and Shadow in 2011 and Daystar in 2012, completing the Firebird Saga.

Tyers remarried in 2014 and is active in the Presbyterian (PCA) church.
