Mark Sperring is a picture book superhero. He doesn't do sumo-stomping, ninja-popping or kung-fu leaping, but he does write exciting, fast-paced, all-action adventures that are guaranteed to save any reader from boredom! Mark studied at Bath Academy of Art and Camberwell College of Art before working as a printer and a bookseller, and later becoming a children's book author. He lives in a homely hideaway in Bristol. Sarah Warburton - super-talented, super-illustrator, superhero - works in a studio at the bottom of her garden. Whenever she gets in a panic (which isn't very often), she knows just the people to call. The Don't Panic Gang is her first book for Bloomsbury. Sarah also lives in Bristol in a homely hideaway (but not the same one as her superhero pal, Mark Sperring).
