Katie finds the stone in an old box in the loft. It doesn't look like much at first, but then it does something amazing: it grows! Katie thinks it's wonderful. What's more, it's hers and she's not going to share it; it's bad enough having to share Mum with her little stepbrother, Jake. It might even be a way of getting in with Sarah and her gang. Meanwhile the stone continues to grow... and grow!
