There's a lot going on in Harry's fifth year at Hogwarts. It shows mainly about the Ministry taking over Hogwarts and so doing a lot of ridiculous changes and putting stupid Decrees through out the year. And yes i loath Dolores Umbridge. She has reached the top of my list of the most annoying people ever! The Dumbledore's Army is really amazing because I think it has bring all Houses - except the Slytherins ofcourse - together with a great born of friendship and togethernesss. The story however, very much like the previous one, ended with a loss. Quite heart-breaking.
