J. D. Fennell was born in Belfast at the start of the Troubles, and began writing stories at a young age to help understand the madness unfolding around him. He devoured a diverse range of books - his early influences include Fleming, Tolkein, Shakespeare and the Brontes. He left Belfast at the age of nineteen and worked as a chef, bartender, waiter and later began a career in writing for the software industry. These days he divides his time between London and Brighton, where he lives with his partner and their two dogs.

'Sleeper is an exciting tale with pace and surprises. J.D. Fennell can write up a storm.' JAMES PATTERSON
