I've been reading space bios almost constantly for the last 8-9 years and this one remains my favorite, from the first chapter "The Four Inch Flight" to Gene's arrival at Patrick AFB to be greeted by Gordo Cooper in his Chevy convertible. Gene Kranz wasn't a by-the-book guy in the space program, he's one of the key people who wrote the book on flight control procedures. His passion for space exploration comes through in every word. The man in the white vest, who participated in some of the greatest events in history while the flyboys got all the glory. Absolutely essential for any space fan, whether you grew up with it as I did, or you're a kid that wants to go to Mars.
