Otherwise "How Apollo Flew to the Moon" (second edition) by David Woods is outstanding.
Yes, it is outstanding -- to me and to others who are very technically oriented and want to know all the arcane details. In the same category (though much older) I can recommend "The History of Manned Space Flight" by David Baker. It's big, thick and very comprehensive. It starts with Mercury and Gemini and continues through Apollo, Skylab and ASTP, interleaved with as much on the Soviet manned space program as he could find in the mid 1980s before the fall of the USSR. Baker wrote an earlier companion volume called "The Rocket". It covers sounding rockets and ballistic missiles as well as space launch vehicles since they have common origins.
These books might not for those who are primarily into the human interest aspects, but for tekkies they're at the top of my list.
For those into specific aspects of space technology, especially computing, several good books have come out in recent years. The most noteworthy is Digital Apollo by David A Mindell, an excellent look at the development of the Apollo guidance and navigation systems. There is a lot of good material on the design of pilot-machine interfaces and the classic tensions between the engineers who wanted to automate everything and the astronauts who wanted to fly by the seat of their pants, often to an unrealistic degree. Did you know that most manned launches give the astronauts the ability to take over manual control during launch? It's never been invoked, nor do I think it likely that it would work, but the capability was there even on the Shuttle.
There's a period cartoon in Digital Apollo that sums it all up. One shows a command module barren of everything but three very bored-looking astronauts, one of whom contemplates the only piece of equipment in the cabin: a large "ABORT" button. The other shows a command module crammed with equipment, knobs, switches, dials and meters, with three harried astronauts busily poring over printouts that are floating everywhere.
