Grumpy Gus is back! It's Christmas, but Gus is not a fan. Can this grumpy dog learn to love the season of goodwill?

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 the Gus picture books, which he both writes and illustrates. He considers the Gus picture books to be semi-autobiographical, as the loveable grumpy dog character is based on his own grumpy moods! Originally from County Durham, Chris now lives and works in Barcelona, Spain.
