Wow! I haven't read such an engaging fantasy (horror) novel in such a long time. Thank you Garth Nix for providing the world with such wonderful characters and gripping imagery. I think this book was written for a YA audience but I'm sure most older readers would enjoy it too. Loved it! I've already got the second book in the series, Lirael, and I can't wait to delve back into the world of The Old Kingdom on the other side of The Wall. Highly recommended.
