I loved this book, its the second best in the series after Mister Monday. Garth Nix imagination knows no bounds. He is amazing. Arthurs is off on his adventures again and must free part 3 of the Will of the Architecht and claim the 3rd key to the kingdom. This is a bit tricky as Arthur is only 12 years old and a chronic Asthmatic! But along with Leaf and Suzy Turquoise Blue, he will fight his way through the House and sail the Border Sea with pirates (on a bed at one point) Seriously good book BUY IT!
