Gr 6-9-Arthur Penhaligon, "Lord Arthur, Rightful Heir to the Architect, Commander of the Army of the Architect, and a whole lot of other stuff," continues his quest to defeat the fifth of seven trustees and collect another precious key in the fifth title (Scholastic, 2007) of Garth Nix's series. Arthur's week continues to worsen. Superior Saturday has turned off the elevators. The Front Door is locked to prevent escape. Leaf has been captured in an attempt to bait Arthur into a trap. Lady Friday has challenged Arthur, the Piper, and Superior Saturday to find the Fifth Key and take command over the Middle House. Meanwhile, Lady Friday's addiction to "experiencing" mortal memories is out of control, and Arthur is determined to stop her. The action-packed plot is complex and a quick review of the first four books is highly recommended. However, those new to the series will pick up the main plot while enjoying the distinctive and delightful voices of each character narrated by Allan Corduner. Reluctant readers will appreciate the vivid pictures Nix continues to concoct for his fans.-Lisa Lea Hardey, Library Media Teacher, Sprague High School, Salem, OR Copyright 2007 Reed Business Information.
