David has been an avid SF reader since discovering the books of Andre Norton in 6th grade. He eventually tried his hand at writing the stuff, and made his first professional sale in 2004. He has been a regular contributor to The Grantville Gazette e-magazine since 2004, beginning with that first sale, as well as appearing in Grantville Gazette and Ring of Fire anthologies for Baen Books. He has had a story published in Jim Baen's Universe e-magazine, and 2013 saw the publication by Baen Books of two books by David: 1635: Music and Murder, which collected most of his short fiction, and the novel 1636: The Devil's Opera, on which he collaborated with Eric Flint. He has also co-written The Span of Empire with Eric Flint, the third novel in Eric's Jao Empire series, which Baen Books will publish in September 2016, and is currently available for pre-order. He is currently working on a solo novel project.
