None But Lucifer

None but Lucifer is a fantasy novel by American writers Horace L. Gold and L. Sprague de Camp. It was first published in the fantasy magazine Unknown in September 1939, and later serialized in the revival of Galaxy Science Fiction, March–July 1994. Despite its good reception by the readership and the prominence of its authors, the book remained unpublished in book form for over sixty years, until finally issued as a trade paperback by Gateways Retro Science Fiction in 2002. It is also available as an electronic publication.
