Paper Towns is definitely one of my favorite John Green books!! It's fresh, makes you think about what is important, and just gives you an overall great feeling while reading it! 
 For those of you who don't know, Paper Towns is about a guy, Quentin, a general nerd, in the band, with strange but hilarious friends, who basically idolizes Margo, his neighbor. They were friends as kids, but grew apart during high school, until one night, Margo comes to Q with a list of things to do to solve her problems. The next day, she vanishes, leaving only a few hints, which lead Q and his friends on a road-trip quest to find Margo. 
 As I said,this book is so refreshing! There's no tragedy, no violence, no hate, just a lot of friendship and love and laughs! (I laughed out loud so often while reading this!!) 
 The characters are really amazing and unique! Q is so determined and sweet, Margo has a thing about random capitalization and is looking for a fun way to spend her days, Radar always has the information needed, and Ben is... Ben =p 
 John Green has this amazing ability to create characters that will stick with you for a long time! :) 
 The plot of the book is both simple and complex. I mean, the pranks that Margo pulls off at the beginning of the book, and the elaborate set of clues she leaves is in no means simple, but just the idea of friends sticking together to help another friend, while just living the high school life brings back the amazing simplicity of the plot.
