Dan made his name in the tie-in SF and Fantasy fiction field, selling more than 1.2 million copies in English language of his Warhammer and Warhammer 40,000 novels for Games Workshop’s Black Library imprint. They’ve also been translated into ten other languages. He’s also made the UK fiction charts with original Torchwood and Doctor Who novels. His comicbook scripts, for major publishers such as Marvel, DC Comics and the UK’s 2000 AD, have attracted critical plaudits and strong sales on both sides of the Atlantic.
