Lizzie refuses to speak. She doesn't want to talk to Rory or Jake, her new stepbrothers. Or to Sam, their dad. Or even to her mum. She's completely fed up with having to join a new family, and nothing can convince her to speak 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 she is . .
