To add to what Cobra was saying towards the end, Shaw's Book is good if you have some of the ground work laid in the how's and why's of air combat. It is a very dry, technical book (though it does have a lot of niffty quotes
) I picked it up fairly early in my AH career and I must say the first time through it didn't really help me that much (at least at least from what I could decern). It was very hard for me to translate what I was reading into the MA. Only after I had some experience under my belt that I would go back and re-read some of it and say to myself "oh yeah that's what he was talking about". Unless you're planning on sticking with this game for the long haul like I was the ~$30 investment may not be worth it.
I think someone new to AH and flight sims in general would be best served by looking at some of the free material available online and getting in touch with someone who can show them the ropes. Keep in mind that the learning curve on this stuff is pretty steep. So don't expect too much overnight but stick with it and you'll see improvement. I've been flying a few years now and there are PLENTY of people online that put me in my place night in and night out, but the good news is I'm still learning and that's what keeps the game fun and interesting.
