I gave this book 4 out of 5 stars for its vivid details and the fact that it is based on something that truly happened. It is quite a good book but tended to be a tad bit too graphic at times. It had so much detail that you could actually get the feeling as if you were actually there with the Andes survivors. The heroism, bravery, and courage of these people is what got me hooked on this book and once I started to read it was hard to try and put it down. It never got boring and will always keep you on your toes.
