Author Biography

From an early age Dan Metcalf knew exactly what he was going to be when he grew up - tall. This was achieved before he even got to secondary school and so another career was decided on. The life of a chocolate teapot salesman is however fairly temperamental and so he decided to move to a job which was comparatively reliable - a writer. He has written for radio, screen and magazines but is best known as the author of The Lottie Lipton Adventures (although he is best known around where he lives as `That Weirdy Beardy Guy'). He is a full-time writer and his biggest ambition is write a major children's adventure series and create a superhero comic. Author of: Dino Wars: Rise of the Raptors Aaron Blecha is an artist who designs funny characters and illustrates humorous books. He has also recently authored Goodnight, Grizzle Grump! and Good Morning, Grizzle Grump! (HarperCollins).
