I liked this book. I went in blind and it wasn't anything like I thought it would be. I'm definitely in the minority here and I won't be gushing over how beautiful the story was and such. Perhaps I just failed to connect to the heroine or may be I was just a bit torn up because of the whole awkward love triangle going on here. 
 I liked both Gus, heroine's best friend, and Keller, heroine's boyfriend. I just never really fell in love with either of them. Not to say that their character development wasn't thorough but there was just something off for me, I can't quite place it. I'll just go with "shit happens" instead of trying to rationalize it :D 
 By the time I was half way through the book I was fully aware of where it was going and how it was going to end. The books is written in a journal format and that, in itself, made it rather depressing for me. And also kind of boring. I wanted to DNF it a couple of times even. A lot of people loved this book and found the story inspirational and you might be one of those people. This didn't quite hit the spot for me but it might for you. ;) One thing to keep in mind, perhaps, is that the book has a major trigger (view spoiler)[cancer (hide spoiler)]
