NASA History Series
These are all of the public history publications by NASA - References, Center Histories, and, my favorite, the 'Project Histories.' This is among the best resources on the site if you're interested in learning about spaceflight - Look into it.

Project Mercury
Project Mercury is a comprehensive book on the Mercury Program. Which was the first manned spaceflight program in the United States. It does a great job at explaining the roots of NASA, the rockets the seven Mercury astronauts flew on, and even the Mercury Program as a whole. However, it is quite information-heavy and not much of a story-telling book. So this is most certainly a book for those out there who are a bit nerdier, such as myself.
Aerospace History
Fire in the Sky: The Air War in the South Pacific. By Eric Bergerud
This is a fantastic record of, as the title says, WWII in the South Pacific. It runs through almost all nations involved, provides a thorough set of information about the technical elements of the aircraft, and the experience of aircrews, and discusses the strategic proceedings of the theatre. If you have a few spare pesos, it's worth a read.
