Edwardo the Horriblest Boy in the Whole Wide World [EPUB ebook] 

Edwardo is an ordinary boy, so sometimes he can be a bit grubby or clumsy, a bit cruel or noisy or rude. The more that he is criticised, the worse he becomes, until one day they call him 'The Horriblest Boy in the Whole Wide World’. Just then, Edwardo’s luck begins to change, and a series of chance events reveal that really he is a lovely boy, and has been all along.
