Kate's grandfather has died and she's missing him desperately. Her Mum wants Kate to talk about it, but that only makes Kate angry. Granddad has gone and he's never coming back. At least she has her toy tiger, Amos, to keep her company. It was a present from Granddad, and somehow holding him close makes Granddad seem less far away. But she doesn't expect Amos to turn into a real tiger—a big, comforting, friendly tiger who smells of Granddad, and sounds like him too.
