Chris Chatterton is a bestselling children's illustrator. He began his career in graphic design and animation, working on projects including Dr Who. Since then he has gone on to illustrate multiple books for children, including the bestselling Ten Minutes to Bed series. For Macmillan, Chris's books include I Am Dog and the Gus picture books, which he both writes and illustrates.
