5/5 (such a surprise, right?) 
 I've only ever read the 5th, 6th, and 7th books because I do not have the first 4 in possession and I have been terribly disappointed in myself for not reading them sooner... 
 But at the same time, it feels like I can experience my first time discovering Harry Potter again doing this, so I think it worked out in the end. 
 Plus, now knowing what does happen later on makes reading this a lot more fun because so many things are hinted here for later books and I get so excited when I read them.
