David was born in Bristol and grew up with his two younger brothers between the Cotswolds, Wensleydale and Lincolnshire thanks to the transient life of having a Methodist minister for a dad. Aside from having a huge number of hobbies including: caving, camping, climbing, archery, shooting and music, David also wrote avidly. Although he had his first book published aged 18, it's taken many more years and life experiences to lead to writing full time, including seeing two ghosts, being mistaken for a homeless person, working on a salmon farm and almost drowning. David now lives in rural Somerset, with his wife and two boys, and still can't believe how his life has worked out.
