A Waterstones Paperback of the Year! What happens when you feel stressed? Maybe you start sweating, or your heart beats faster. When Charlie McGuffin gets stressed, something a little bit different happens: he turns into an animal! Unfortunately, things are getting quite stressful for Charlie: - His dad's business is in real trouble - He might have to move in with his Aunt Brenda and her seventeen cats (and wooden leg) - And it's getting harder and harder to control his powers Luckily, Charlie's best friends Flora, Wogan and Mohsen are on hand to help. If they can break into the fortress-like offices of Van Der Gruyne Industries and recover the McGuffins' stolen gold, maybe Charlie won't have to move away after all. Can Charlie's friends help him master his powers once and for all, or will he end up stuck as a pigeon forever?
