I am glad I read John Green's books in the order that I did. ("Looking for Alaska", then "An Abundance of Katherine's", now "Paper Towns"). There are similarities between all three, but they are all different as well, and he has certainly perfected his skills as a storyteller. 
 I have gotten used to his style and his characters, and quite enjoyed all three parts which make up "Paper Towns". His characters felt a lot more fleshed out this time around, and I quite liked the ending. I even had some laugh out loud moments in the van on their hasty "road trip". 
 I would have enjoyed reading this while I was at High School had it been written back then. 
 I'm now looking forward to seeing whether the movie did the book justice.
