This book finished ooff the Bartimaeus Series perfectly, and unlike most books did not get boring or repetitive in the last couple chapters, instead staying true to his classic humor-filled theme. Bartimaeus, Kitty, and Nathanial all play starring roles in this, with a plot twist at the end that will leave you both satisfied and stunned. All in all, this is one of the best fantasy books you can read, maybe even rivaling Harry Potter.(almost)
