The second book in the Harry Potter series, Harry Potter and the Chamber of Secrets is written from the point-of-view of the now-12-year-old Harry Potter. The book's title refers to a chamber which was, according to legend, created somewhere in Hogwarts castle by one of the founders, Salazar Slytherin, when he departed Hogwarts; much of the book's action revolves around that chamber, and what may be inside it, if, in fact, it actually exists.
In Harry Potter and the Chamber of Secrets, we begin to see the darker side of the wizarding world that we were introduced to in Harry Potter and the Philosopher's Stone. In this story, Harry is not seen only as The Boy Who Lived by his fellow students, but instead as a suspect, as many believe him to be the heir of Slytherin, and thus the force behind attacks on students in the school. Further darkening the atmosphere is the history of Hogwarts itself, including some highlights of arguments between the Founders. We find that while Hogwarts has become, in a way, Harry's new home, his safety is not assured there, as this new threat comes from within the castle itself.
