The Perks of Being a Wallflower by Stephen Chbosky. One of the most amazing books I've ever read. I loved this book practically as soon as I started reading it, it was that good. It's odd to think how so much could happen to one boy, in a sense that it doesn't seem real. But in the same way it does feel so real and that you can identify with it completely. It's great, and if you've never had a chance to read it, seriously do! Because you won't regret it.
I now have basically every book mentioned in it on my "to read" list :p
