Query: Like mystery books?

Harry Potter and the Chamber of Secrets by J.K. Rowling is a fantasy story with exciting characters that keep you reading until the end of the book. The plot of the story is at Hogwarts. It's Harry's second year at Hogwarts and Ron's sister Ginny comes to Hogwarts for her first year. Strange and mysterious things will happen that not even the Headmaster Albus Dumbledore. Also an old student comes back to haunt their memories. I would recommend this book because every chapter is a mystery. It is a very,very,very awesome book.
