"What a treacherous thing it is to believe that a person is more than a person." 
 OK, I had trouble rating this. At some point I thought it would be a 3-star book,but in the end I couldn't settle for more than 2 stars. I have to admit,though, I did enjoy some parts. The first 1/3, where Q and Margo have their nighttime adventure is actually very funny and intriguing. But after that, the pace slows down and nothing really happens for a long time. Quentin is just looking for her in each and every abandoned building around their town,while reading the same poem over and over again. Fortunately,just before the end, we get to see some action again. 
 When it comes to the characters, I liked the secondary ones, especially Ben and Radar. They were clever and amusing of course,because they are Green's characters,but still resembled real teenagers,worrying about prom,graduation,girls and trying to have some fun now and then. On the other hand, I found Quentin a bit unconvincing.He doesn't have any interests,except obsessing over Margo Roth Spiegelman. I mean,why would he spent so much time thinking about her, a girl who hasn't spoken to him since they were nine years old? And on top of that, he gets angry with his friends when they spend some time doing normal teen-stuff, instead of discussing his imaginary girlfriend all day long. As for Margo Roth Spiegelman,well, I must have read her name over a million times, but I never managed to understand what was actually going on inside her head. Maybe that is exactly the point, but the thing is that to me she sounded so silly (view spoiler)[leaving school just before graduation in order to live in an empty barn and meanwhile criticizing everyone else for their choice to act like adults and graduate and go to college. Guess what Margo,dumping school doesn't make you sophisticated, it just ruins your prospects in life. Or maybe you don't mind living with your parents' money in empty barns,but that doesn't sound so rebellious,does it? (hide spoiler)] 
 I liked the ending though, I think it was the only suitable ending. (view spoiler)[Quentin finally realized that Margo is not-so-perfect after all and that he should actually go on without her. It was about time,Q. (hide spoiler)] Because after all, no one is perfect, and we shouldn't expect them to be,clinking to them like they are everything that is good in our lives. Quentin in his journey to find Margo had his own big adventure with his friends,the people who actually really mattered in his life. I just wish that the book had focused more on that aspect of the story, rather than the deciphering-Margo one. 
 "Like each of us starts out as a watertight vessel. And these things happen - these people leave us, or don't love us, or don't get us, or we don't get them, and we lose and fail and hurt one another. And the vessel starts to crack open in places. And I mean, yeah, once the vessel cracks open, the end becomes inevitable. Once it starts to rain inside the Osprey, it will never be remodeled. But there is all this time between when the cracks start to open up and when we finally fall apart. And it's only in that time that we can see one another, because we see out of ourselves through our cracks and into others through theirs. When did we see each other face-to-face? Not until you saw into my cracks and I saw into yours. Before that, we were just looking at ideas of each other, like looking at your window shade but never seeing inside. But once the vessel cracks, the light can get in. The light can get out."
