Kay Kenyon is the author of over a dozen acclaimed novels of science fiction and fantasy, as well as numerous works of shorter fiction. She published her first novel, the time travel adventure The Seeds of Time, in 1997. Leap Point followed in 1998, and the space opera Rift in 1999. Her 2001 novel Tropic of Creation was a preliminary nominee for the 2001 Endeavour Award. Kenyon's next works were two loosely-connected SF novels: Maximum Ice (2002) and The Braided World (2003). Maximum Ice was nominated for the 2003 Philip K. Dick Award; Braided World for the 2004 John W. Campbell Memorial Award.

From 2007-2010 Kenyon produced the 4-book vast fantastical epic The Entire And The Rose, set within The Entire, a five-armed radial universe that exists in a dimension without stars and planets and is parallel to our own universe. Each of the first three books in the series - Bright of the Sky (2007), A World Too Near (2008), and City Without End (2009) - was nominated for the Endeavour Award. To date, her other major series has been the Dark Talents series (2017-2019), a fantasy series that takes place in the years immediately before World War II and tells the story of a war of magical espionage between Great Britain and Nazi Germany.

Kenyon was born in 1956 in Milwaukee, Wisconsin. She currently resides in Wenatchee, Washington.
