Jason started writing for children 20 years ago when he landed a job as the fresh-faced reporter on the Young Telegraph. His enthusiasm for innovative and inspiring children's writing has stayed fresh as ever it was. His face hasn't. Now with beard, one shade of grey, Jason has created books and multimedia on a huge range of non-fiction topics.

When he's not writing, Jason helps run Calder House, a special school where children with specific learning difficulties, not only learn to read, but learn to love reading.

The Sheep that Saved Christmas is his first picture book.

Adrian Reynolds was born in South Wales, and after studying at Swansea College of Art and later at Cambridgeshire College of Art and Technology, Adrian worked at Heffers Children's Book Shop before beginning to write and illustrate his own picture books.

Adrian's very first books were published in 1997 and since then he has published more than forty titles, including the hugely popular Harry And The Bucketful Of Dinosaurs series, written by Ian Whybrow. He has won the Red House Picture Book Award and the Sheffield Children's Book Award.
