Review title: Good, but a little shallow
Product review: This is a very readable biography of astronomer Carl Sagan. Although he did a poor job on Sagan's childhood, the author dug up a wealth of interesting facts about his life. The one problem I had with this book was that Poundstone ignored the "themes" that reappeared throughout Sagan's life, or at least didn't point them out. Read along with Keay Davidson's biography of Sagan, which has fewer facts but more connections.
