Stephen Giles was born in Sydney and has lived there most of his life. He has been a professional writer for the past ten years, writing children's fiction across two different series – Silas and the Winterbottoms and Ivy Pocket (written under the pseudonym Caleb Krisp). Prior to that Stephen worked in a variety of jobs to supplement his writing including market research, film classification and media monitoring. But for him, all roads led back to writing fiction. The Boy at the Keyhole is Stephen's first novel for adults.
