"an fascinating book, but better on paper"
This book is clearly recognizable as coming from the same fine intellect as "Guns, Germs and Steel." However, it suffers from two problems unique to the audiobook format. The first problem is that the logic suffers somewhat from the abridgement. Even worse, as a scientist I found it very irritating not to be able to consult the figures, diagrams, and references that come with the paper copy of the book. I definitely recommend buying the hardcopy instead of the audiobook. However, the points that Jared Diamond makes in this book are so interesting and important, and are so well-illustrated with anecdotes about various cultures, that I have to say: if the audiobook version is the only way that you will read this book, than by all means buy it.
"an engrossing story"
A great novel, with excellent narration. It's not fair to classify this book as "fantasy" because the story is so well-developed and intelligent. The thirty-plus hours of this book actually felt too short, and I hope a sequel is forthcoming!
"an interesting overview of autism"
This set of programs is a nice balance of perspectives on autism. The hosts speak to people who have autism, and scientists who study the disease. The interviews provide accurate scientific information and a human perspective on this devastating condition. Highly recommended.
