Query: A brilliant book

I thought that this book was quite amazing. It combines normal Helen Cresswell writings with a touch of fantasy and mysticism yet it still remains light and easy. I would recommend this book for young fantasy lovers as I read it when I was 9 and thoroughly enjoyed it and I still read it now even though I'm 13! You're bound to love this book because it really is one of Helen Cresswell's best.
