This book was seriously amazing! I couldn't wait to get it when I saw it on here. At the beginning you had to think back to "Lady Friday" which was funny, as I couldn't remember the storyline very well before hand.
The only thing that annoyed me was Arther, He seems to becoming a bit of a snob, but thats what Garth nix wants, so you can;t really complain? Right?
But I have to say "The keys to the kingdom" series are amazing, and I would recommend them to any who fancies a good read, be you child or adult!
