Born in Dublin in 1973, Oisin spent his childhood there and in Drogheda, County Louth. Later in life, he left for London to seek his fortune. Following three and a half years of working in advertising he became increasingly concerned for his immortal soul and returned to Ireland much as he had left - with no job, no home and some meagre savings.
Ever the optimist, he now works as a freelance illustrator and mercenary artist by day and escapist writer by night. He hopes one day to have a decent job, with a pension, a health plan and paid annual holidays.
