So yeah I gave 5 starts to this book. 
 " And I swear, at that moment, we were infinite" 
 Even though it wasn't an "happy book" I found it refreshing. It discusses many issues that teenagers will face during high school but isn't glorifying it nor bringing it down. It's simply factual; Charlie tried this or that drug. It doesn't say implicitely that the reader should try it as well or shouldn't. 
 I also liked the form of the book : Letters. You get some back up information when Charlie needs to but you don't know too much either... It was nice and simple. 
 Throughout the book, I asked myself a lot of questions about whether Charlie was "normal" or not. But in the end, it just doesn't matter. He's a troubled boy, like many other troubled boys, who describes his first year in high school with all the questionning that comes with it. 
 In the end, it makes you realize (and wonder) if you are truly yourself all the time. Are we true to who we are or do we simply put on "masks" depending on whom we're with? I think that's the whole point of the book... 
 I had borrowed that book from a friend but all probably try to get a copy.
