Sheldon's New Shell is published in partnership with Surfers Against Sewage, the charity that acts to clean up beaches around the UK.

Lily grew up in the wilds of snowy nowhere, spending much of her time talking to animals and making up stories. She has continued to do this in her adult life, and now writes both fiction and non-fiction books for children. Her titles include big books about dinosaurs (Dinosaurium), rhyming books about dinosaurs (The Dinosaur Department Store) and stories about escapee hot dogs (Hello, Hot Dog!). Her latest title for Buster Books (Calm Down, Cooper!) features a very naughty parrot and a conscientious puppy. Follow Lily on Instagram and Twitter @lilymurraybooks.
