Rosemary Edghill is a pen-name of Eluki Bes Shahar.
She was born long enough ago to have seen Classic Trek on its first outing and to remember that she once thought Spock Must Die! to be great literature. As she aged, she put aside her fond dreams of taking over for Batman when he retired, and returned to her first love, writing. Her first SF sale (as eluki bes shahar) was the Hellflower series, in which Damon Runyon meets Doc Smith over at the old Bester place. Between books and short stories in every genre but the Western (several dozen so far), she's held the usual selection of odd and part-time writer jobs, including bookstore clerk, secretary, beta tester for computer software, graphic designer, book illustrator, library clerk, and administrative assistant for a non-profit arts organization. She can truthfully state that she once killed vampires for a living, and that without any knowledge of medicine has illustrated half-a-dozen medical textbooks.
Her last name -- despite the efforts of editors, reviewers, publishing houses, her webmaster, and occasionally her own fingers -- is not spelled 'Edgehill'.
