Well it was a very smart book that had really intellectual humour so if u don't get it .... Well coz I greatly admired it . I have never read a book like this in my whole life ... But I'm 14 so it's OK .Ok?It's really philosophical without getting philosophical .a narrative about life and death and the love caught in between ... I'm in infinite luv with hazel and gus and their breakfast theory ..... Must be read and understood .
