Query: Entertaining read about a fascinating time.

This book was well worth the effort. I walk away with two major impressions: one, wow, what an achievement the Apollo program was and two, double wow, what an ego these astronauts had. I found their achievements to be inspiring, but their human persona left a lot to be desired. But I appreciate the honesty, the author could have easily glossed over that.
