John Dougherty was born in Larne, Northern Ireland. He studied psychology at university and, after a number of different jobs, became a primary school teacher. Whilst John was teaching, his interest in children's literature was reawakened and he soon began writing stories. His books have been shortlisted for a number of prestigious awards and he recently won the Oscar's Book Prize, along with Laura Hughes, for the picture book There's a Pig Up My Nose. Katie Abey has illustrated a number of books including the brilliant We Wear Pants picture book. She has also produced work for the stationery and greeting card industries. Her artwork can be found in many stores such as W H Smith, Urban Outfitters, Paperchase, and Scribbler. Her fun and anarchic art style is perfectly suited to the Clark and Shark books and she has brought them vividly to life.
