Harry Potter and the Chamber of Secrets is the sequel to the very first Potter book and tells about the boy's 2nd year at Hogwarts. Numerous writings on the school's walls warn about the next big danger: heir of Slytherin is set free and he's coming after the kids who don't have pure magic running in their veins. The messages are always coming up on the walls after terrifying attacks that freeze everybody in the school.
So, Harry and two of his closest friends start investigating these rapid attacks and try to figure out what's really going on and how they can defeat this strong new enemy. The 2nd novel in the Harry Potter series was introduced to the public in 1998, a year after the debut novel was published and got a lot of positive feedback from the reviewers and the fans.
Young boys and girls really loved the gripping, exciting journey that Harry and his team embark on, and the critics praised the author for moving away from the "overly childish" plot of the first book (however, other reviewers claimed that the story was a bit too "adult" and might scare the children). The Chamber of Secrets talks about the importance of sacrificing yourself for the people you love and staying true to your beliefs.
Plus, Rowling shows that a boy's/girl's character is defined by his/her actions and choices, nothing else. Personal identity is a central theme and Rowling touches the subject of racism and non-equal treatment of people who are just different. The second book about Harry Potter proved that J.K. Rowling is a really talented writer that can appeal to both the younger readers and their parents and is capable of writing fun, intriguing, funny and educational books.
