"Cosmos" is so much more than a science book. It's a history book and a book That teaches so much about life and where we are headed. This book taught me so much about what is out there and how we are all related. "Cosmos" is exceptionally readable and you want to keep the pages turning. Sagan Seems to sum up the heavens and the earth all in one fantastic book. Read it not just to learn about evolution or astronomy, but to get a clear view of how the universe really works and how we relate to it.
