"Harry Potter and the Prisoner of Azkaban" was excellent. The books say ages 8-12, but I, like so many others, am older and enjoying them. This series easily ranks with J.R.R. Tolkein, Roald Dahl, C.S. Lewis, Philip Pullman, and Lewis Carroll. The stories have great, twisting plot lines and this new one especially had a more mature thread to it. J.K. Rowling has a knack for bringing her characters to life-I often find myself wishing that I could jump into the book to slap Malfoy, Snape, or the Dursleys. The rivalries are great fun. I see trouble brewing between Cho Chang and Ginny Weasley. I wish that I weren't a Muggle and could experience Hogsmeade, Quidditch, Hogwarts, and Diagon Alley.
I hadn't heard of the series until June when my 11 year old brother got the first one. I did not expect to enjoy it as much as I did, but now I have read all three. I read "HP and the Prisoner of Azkaban from 2 AM to 2 AM the next day. Since I read them all in the span of a month, it is now a shock to have to wait a year for the next one. Thank you Ms. Rowling for giving me an excellent excuse not to read my summer reading books yet.
