In this book, Harry Potter and the Chamber of Secrets, by J.K. Rowling, Harry has to find out who is behind petrifying certain kids at Hogwarts. At first, people think it is Harry himself, but when Hermione, Harry's friend, is also petrified, they give up their theory. Harry has to find out who is behind this mess before everyone at Hogwarts is petrified, including Harry, too! As Harry later finds out,this might have something to do with a snake called the basilisk, and even the villain,Lord Voldemort himself! Read this amazing book to find out! I loved it!
