I've been on a bit of a space book binge lately, and I'm currently about half way through the second book in Boris Chertok's (Sergei Korolev's deputy) four volume
Rockets and People series. It's quite fascinating but does require some patience. There's a reason, I suppose, why you never hear about the great Russian editors.
My last three space book reviews:
Picturing Apollo 11
The Soviet Space Program: The Lunar Mission Years: 1959–1976
Apollo to the Moon: A History in 50 Objects
