This book quite literally changed my life. I found it lying around the house when I was sixteen, left by my college-bound older sister.
The fact that I, at the time generally bored by nonfiction, consumed this book is a testament to its compelling and captivating nature. Sagan holds our universe in awe and conveys a sense of wonder to the reader that gripped me and changed my views forever.
A book primarily about our future as a species, it covers astronomy, evolution, and engineering in an effort to explain why we must progress beyond our home world. The world would be a better place if this was required reading for everyone.
