I'll add to the list of recommendations "V-2" by Dornberger.

https://www.amazon.com/Nazi-Rocket-Weapon-Walter-Dornberger/...

Although Dornberger was not an engineer, the book does go through many technical difficulties and how they were resolved. The V2 is, of course, a direct ancestor of the Saturn V, and the solutions to those difficulties are present in the SV as well.
