This is a completely different survival story. It feels contemporary, and it does recognize previous similar experiences (Alive, the story of the Uruguayan rugby team who were involved in the crash of Uruguayan Air Force Flight 571, which crashed into the Andes mountains on October 13, 1972 in which survivors had to resort to consuming some of their dead) although this survival story does not devolve to this point.
There are several poignant moments, and the characters are portrayed in all their flawed glory. I like this - definitely not my normal book - but worth a foray nonetheless.
The story of the protagonist's experiences on a mountain in the desert near Palm Springs with three women speaks to the resilience of the human spirit, and also to the mistakes we may make along the way. Again, there is a thread of redemption, making errors in judgement, and of choosing different paths. There is also an element of the spiritual, and there were some passages that really struck home. If you are looking for a different kind of read, this is a fairly quick, well written choice. You are told pretty early on that not everyone makes it, and there is a real twist at the end of the book. I found it was just "long enough" that by the time I was finishing the story, it was time (if that makes sense).
