A charming reissue of a classic Judith Kerr backlist treasure with a beautifully refreshed new cover look. When Willy is told he's not allowed to bring his pets to his sister's wedding, despite his promise, they turn up anyway... with disastrous results! Once there was a boy called Willy. He had lots of pets and a grown-up sister. Willy's sister was so grown-up that she was getting married, and Willy was going to the wedding. Shall I bring my pets to the wedding? said Willy. No, said Willy's father. No, said Willy's mother. No, said Willy's grown-up sister. Better not, old chap, said Bruce, who was going to marry Willy's sister. Your pets might not like it. Despite Willy's attempt to keep his beloved pets from coming to his sister's wedding they some how manage to find a way in to the church and the even the reception afterwards, with disastrous results! This is a charming, hilarious and beautifully illustrated story from the author of the perennial children's classics 'The Tiger Who Came to Tea' and 'Mog the Forgetful Cat'.
