The good news is that Bartimaeus is back. The bad news is that there's not enough of him. What made the first book in this series a standout was his sarcastic commentary, self-aggrandizing descriptions, witty banter, and delightful footnotes detailing the workings of magic and demons in this alternative world. They're all still here, just less of them.
Meanwhile Nathaniel and Kitty alternately take center stage in a complex and often exciting, if too loosely edited, adventure involving, among many other things, grave-robbing, a demon living in Gladstone's bones, political intrigue, war, werewolf police, destruction, and a shadowy figure who seems to be playing all sides like puppets. Nathaniel, one of the least likeable main characters in children's literature, continues to fascinate and frustrate the reader with his growing power -- and obtuseness. The stage is clearly set for a grand finale in Book 3, presumably including Nathaniel's reclamation.
