I am a professional writer and games developer, best known for my fourteen years with Games Workshop and (so far) for my Black Library novels and short stories. In March 2008 I departed GW to concentrate on my freeelance writing. So far, so good.
You can find a list of my Black Library books here. I have also written many Warhammer and Warhammer 40,000 short stories, most of which can be found one way or another in the various collections and anthologies available.
