So... this was the first John Green book that I ever read, and this is probably why it gets three stars whilst the others got like one. 
 So, to begin with the cover is Awful. Like, what the fuck? I wish my bookstore got the one with the smoke on it or even the daisy! But, never judge a book by its cover! 
 So, it was okay, basically! The characters were alright, though they all fucking love reading, because John Green has some weird superiority issue with how great 'nerds' and 'intellectuality' is, and that always leaves a weird taste in my mouth. Like, well done, you enjoy reading, well fucking done but you're not superior to people who don't? 
 So, the characters: There is a weedy and unremarkable guy with a ~~quirky hobby~~ which is last words of people. There is also an interesting and cool girl, but wait! She's crazy! And then she dies, because she forgot her dead mums birthday whilst cheating on her boyfriend with unremarkable weedy guy. Oh, and weedy unremarkable guy cheats on his unremarkable girlfriend who he never really liked, but I don't think she cared that much either. 
 It wouldn't be an issue! But all of his characters are so much the same. Like, they all love reading and they're all intellectual and brilliant, and the girls are always cooler than the guys and it just gets really, really boring! Stop jerking yourself off to your own intellect, John! You can't create an individual character for anything! They all talk the same! 
 What I can say positive for this book is that there are no ridiculous lines that I can remember, I heard someone call them "literary lighthouses". Yes, I am thinking of this: "My thoughts are stars I cannot fathom into constellations." Calm down, John!
