I LOVE THIS SERIES!!!!!!!!!! I finished this book in under 2 days it was so good. In the start it involves Harry inflating his aunt Marge and going to live in Diagon Alley for a while. Around the middle, he gets a new "Firebolt" broom, Hermione goes to two new classes and her schedule has two classes at 9:00 and two at 2:00, and Harry gets attacked by dementors. Near the end, Peter gets away ( I won't tell you who that is) and Gryffindor wins the house quidditch cup. IT IS A GREAT BOOK!!!!!!!!!!!!!!!!!!!! Six out of five stars!
