A must-read if you believe in rational thinking. One of the most terrifyingly relevant books published in 1996.

Sagab is brilliant and Cary Elwes (along with Seth MacFarlane) do a great job with narration. This book has inspired me to question what I don't know to combat fear with curiousity. 

However, because of the time this book was written in, though Sagan was progressive for his time, while his science is sound, some of his beliefs were dated.
