Encouraged to write fantasy at a young age by the late, great Sir Terry Pratchett, David first appeared alongside his hero in the anthology Knights of Madness in 1998. Recognised for the comic-timing in his writing, he was then taken on by Douglas Adams' agents, Ed Victor Ltd and became an EV client exactly a year before his first breakthrough book deals with Hodder in the UK and Disney in the USA.

Between 1998 and 2016, David wrote fantasy and YA books for some of the biggest publishers in the world. These included The Illmoor Chronicles (for Disney and Hodder), Gladiator Boy and Undead Ed (for Hodder and Penguin), Davey Swag and Outcasts (for Hodder). His books have been converted into audio works for BBC Worldwide and Random House and translated into fifteen different languages by companies including Sony in Japan. 

David’s short stories have also appeared in a variety of anthologies, including the celebrated Knights of Madness (with Terry Pratchett, Tom Sharpe, etc) for Orbit and Penguin, edited by the late and great veteran fantasy anthologist, Peter Haining. David has also written review columns for Interzone and SFX and fictional histories for Games Workshop and their Warhammer universe. In 2022, David and his wife Chiara set up Kingsbrook Publishing, an independent publishing company that focuses on fantasy and children's books. They have steadily been republishing his original work along with some brand-new stories to bring them to a new audience.
