Billions & Billions

*A "New York Times Bestseller"

In this book, his last, Carl Sagan again demonstrates his extraordinary ability to interpret the mysteries of life and the majesty of the universe to the lay reader. He provides clarity and understanding for an audience eager to make sense of the world and goes beyond that as he illuminates the strongly held belief that we have the ability to change things for the better.

In their posthumous award to Dr. Sagan, the National Science Foundation declared that his "research transformed planetary science, " and that "his gifts to mankind were infinite."
