Well, I read it in one shot. From approximately 3am until roughly 7am, I sat in a chair and read all 300ish pages. That automatically qualifies a story for four stars. 
 The characters in the book were great. I've read the complaints and can agree with most of them, but at the same time I actually know people like Quentin and Margo. Or, I guess I should say that I imagine the people I know are like them. 
 What made me give it five stars was the fact that it provoked me to think. A lot of books are fairly straightforward and don't require a whole lot from the reader other than time and a pair of eyes. There were a few things plot and pacing wise that annoyed me, but nothing too bad. I shakily recommend it!
