The Perks of Being a Wallflower

I am half way through "Perks of Being a Wallflower" and I'm enjoying it a lot. One of my favorite things about it was how it is written in letters. I'm sure the author must've had some trouble doing this, since the letters all have to be in past tense, and all of it is pretty much just re-telling what happened. Another thing i like about the book is how mysterious is it. "I will call people by different names or generic names because I dont want you to find me" says Charlie in the book. I'm about half way through the book and I still have no idea who Charlie is actually writing to. Its almost as if Charlie is writing more of a diary than letters. But hte style of writing int the only good thing about the book. The topic is simple, but still very interesting. It's a sweet story where a little nerd starts to make friends and actually start to be liked and not become such a "wallflower".  Though I still have a lot left in the book, I can tell I'm going to enjoy it a lot.
