Harry Potter just wanted to be able to go to school without trouble but Voldemort was out to kill him and destroy the school. So Harry, Ron, and Hermione decided to put a stop to this by finding out who is behind all the trouble in the school. Then they are able to defeat Voldemort by finding a way to kill part of his soul that will later in the series help finish Voldemort. Now they are able to finish the rest of the school year happily.
I really loved this book because of the draw it had on me to never put the book down. I also liked the balance between adventure and mystery in the book.
