Bravo! I am writing this review just now (some two weeks after reading this book) because it's only now that I felt comfortable going back to the words I've read and the emotions I felt while reading (especially with the ending). 
 As usual, I LOVE this book because I LOVE playing detective. I love how the writer keeps me flipping through the pages, hungry for more information. I like to piece things up to see the bigger picture. Stephen Chbosky is a genius! He has not only been successful in capturing my emotions (which is pretty easy when it comes to me), but he also has captured my thoughts. I seriously have been disturbed for several days. And I'm saying that with complete honesty. 
 I can't believe I didn't saw the "twist" coming. 
 While reading through the main character's letters though, I have realized he was mentally disturbed and it took me back to the days I was on duty as a psychiatric nurse. 
 I have never expected the book to have this effect on me. Swear.
