This was a tear jerker, though I should say I didn't actually cry. 
 The story is about Hazel, a teenage cancer patient, who is living on borrowed time with the help of an experimental medicine (Which John Green mentions in the afterword as 'doesn't exist yet':p). She has to deal with the way her illness affects her parents' lives and the pity and cluelessness people feel around her. On her mother's insistence, she goes regularly to a support group, where she meets the charismatic 17 year old Augustus, the friend of one of the support group fellows. 
 It was funny and poignant and it made me think a lot. The language felt at times too flowery/deep for the teenage protagonists; but in my brief life I've met a lot of people who wouldn't be confined into prejudices; so well.. I'm being open-minded about it. There were a lot of lovely quotes throughout the book E.g:- "I fell in love the way you fall asleep: slowly, then all at once." Isn't that such a beautiful line? 
 After reading the book, when something went wrong, my initial thought was "Well... the world is not a wish granting factory" :) . It was not a typical romance book (view spoiler)[ where everything was wound up beautifully and the hero and heroine walked hand in hand towards their happy ever after .It didn't even have a conventionally proper ending for that matter (hide spoiler)] But it wasn't expected anyway. It felt realistic and the characters were relatable. I can't exactly point out why I'm not giving it 5 stars, but it is definitely going to my 'favourites' shelf.
