Jeanne Cavelos is a best-selling writer, an award-winning editor, and the director of the Odyssey Writing Workshops Charitable Trust. She began her professional life as a NASA astrophysicist. Her love of science fiction sent her into a career in publishing and she became a senior editor at Bantam Doubleday Dell, where she ran the science fiction and fantasy program and created the Abyss horror imprint (World Fantasy Award winner, 1993). In eight years in New York publishing, she edited a wide range of books, working with such award-winning and best-selling authors as William F. Nolan, Robert Anton Wilson, Joan Vinge, Tanith Lee, Kathe Koja, Poppy Z. Brite, and Peter Dickinson.

Jeanne left New York to pursue her own writing career. She has written four novels set in the Babylon 5 universe—The Shadow Within (Dell, 1997/Del Rey, 2003) and the bestselling The Passing of the Techno-Mages trilogy, made up of Casting Shadows (Del Rey, 2001), Summoning Light (Del Rey, 2001), and Invoking Darkness (Del Rey, 2001). She's also written two nonfiction books—The Science of Star Wars (St. Martin's Press, 1999; New York Public Library's Recommended Reading List selection) and The Science of The X-Files (Berkley, 1998; Bram Stoker finalist)—and edited the anthology The Many Faces of Van Helsing (Berkley, 2004; Bram Stoker finalist). Her short fiction has appeared in a number of magazines and anthologies. She is currently writing a biological thriller, Fatal Spiral.
