Shoo has written and illustrated over sixty children's books and is the creator behind many well-loved characters, including the Jets series (A&C Black), The Ginger Ninja and Rex Files (Hodder), Oxford Reading Tree titles and picture books including Cat in a Flap and Hey Diddle Diddle (Puffin).
He illustrated the wonderfully warm and collectable Colour Crackers series, written by Rose Impey, and these have proved to be so popular, that he has re-illustrated them in full colour. Shoo also writes and illustrates the Little Horrors series.
