I've read several books about the Apollo program. Sadly, the focus of those books is always on budgets, management, personalities, and politics. Just a few technical tidbits are thrown in here and there.
Personally, I'm much more interested in how problems were identified and overcome than how The Trench was organized and how astronauts liked to speed in their corvettes.
I would recommend _Apollo_ by Charles Murray and Catherine Bly Cox. It covers the program from the perspective of the engineers who were involved and the technical problems they had to overcome. The book is currently out of print but is available for the Kindle.
