I wasn't going to comment because i haven't read the book or seen the film (though it's on my emergency school holiday entertainment list - moved several places down after reading your post!). I would also have said I had never heard of Susan Cooper but that isn't true. I'm actually reading a book by her at the moment although, I'm ashamed to say, I didn't know she had written it. I'm reading Little Tyke's set book for next term about a boy who is transported back in time to act in A Midsummer's Night Dream ast the "new" Globe theatre (The King of Shadows). I've only just started it but it's pretty good. I was talking to Dad on the phone and noticed the book on the coffee table. I nearly squeaked! If Little Tyke enjoys it (she hasn't read it yet), I'll put her onto thse books. She likes fantasy so I think it might appeal.
