If you want to know more about the Donner party, I would highly recommend this book. The retelling of a tragic events, sticking with the details, and trying to give a feel for what it would be like for the Donner party, make this an excellent reading. It is very hard for most people to comprehend what it would be like to be trapped in the mountains without adequate food or clothing and I think the author did a good job by drawing comparisons with other things the reader might be able to relate to. It is amazing that any of these people survived. I listened to the audiobook version narrated by Christopher Prince. He had a very good voice for the documentary. His voice was very clear and he did not sound opinionated about the topic.
