This is a really well done behind-the-scenes look at the early space race from both the USA and USSR sides. While the focus seemed to gradually hone in on our hero, Yuri Gagarin, as the book went on, there was a lot of interesting information regarding the USA‘s Mercury program and the launches and obstacles that led up to it; and a lot of comparing and contrasting NASA operations with that of the Soviets‘ Vostok space program. Fantastic!
