Paperbacks:
- Eric Hammel, "Aces Against Japan" (and Aces Against Germany)
Nothing but non-stop combat stories from American Aces.
- Saburo Sakai, "Samurai"
One of Japan's top aces tells his stories, including his amazing flight home over hundreds of miles of water after being shot in the head.
- Donald Caldwell, "JG-26"
Great unit history, lots of combat, a microcosm of the rise and fall of the luftwaffe.
Doesn't fit your '3 books' criteria exactly, but these are pretty cheap paperbacks that should be easy to find and all are great reads.
