She was natural inside Hollywood, California and has lived there and within Pismo Beach virtually all of her life. Prior to becoming the agency writer she spent several years around theater, including teaching Elizabethan English as a second language.

She is better known for her "Company" series of historical time travel science fiction. Her number one stories were published around ''Asimov's Science Fiction in 1997, and her first novel, In The Garden of Iden, by Hodder & Stoughton in the same year. More leading light works include Mendoza in Hollywood'' (novel, 2000) and "The Empress of Mars" (novelette, 2003), which was nominated for the Hugo Award.

Her unusual number 1 title (pronounced rather a word "cage") occurs as portmanteau of the names of her ii grannie, Kate & Genevieve.
