A short, sparky book from best-selling author Jacqueline Wilson. Now with a new cover look and introduction by Jacky."Why don't you ever say anything, Lizzie?" said Rory. "It's like you've got a zip across your mouth."Lizzie refuses to speak. She doesn't want to talk to Rory or Jake, her new stepbrothers, or Sam, their dad or even her mum. She's totally fed up at having to join a new family and nothing can coax her into speaking to them. Not football, not pizza, not a new bedroom. That is, until she meets Great-Gran - a member of the new family who is even more stubborn than her – and has had a lot more practice!
