Though similar to book one, this well-written, exciting sequel keeps kids glued to the page. Though it breaks no new ground in the series, the plot is a riveting thrill ride, involving giant man-eating spiders, a ghost who lurks in the girls' bathroom, secret underground vaults, time travel, magical-transformation potions, the near death of several major and minor characters, and a climactic confrontation with the greatest evil wizard of them all, Voldemort. J.K. Rowling excels at twists, turns, and surprises, and many will find the identity of the person who opened the Chamber a complete surprise.
