I really enjoyed the voice, the sarcasm, it was really witty. But! I could predict the ending and it ruined it for me and not because I am heartless. It was amazing how the characters learnt to take their ordeal with a pinch of humour and not being stigmatised with their diseases, searching to lead their life as normally as possible. (view spoiler)[ However, I think the book would have a bigger impact if Hazel really became the grenade she was so afraid of becoming WITH an ending mid-sentence, the same as Anna- that would add a different twist to it...personally (hide spoiler)]
