Penny Worms is a well-known children's book editor who was first encouraged to write by Wallace & Gromit. With Wallace so focused on inventing and Gromit so busy helping him, they needed someone to write books for them, including novelisations for The Curse of the Wererabbit and A Matter of Loaf and Death, plus a book about their Grand Adventures and Glorious Inventions for Carlton. Penny is an enthusiastic Google[trademark] Earth traveller, hoping that one day she will have the time and money to go to more of the places she visits for real.
