HI
Unfortunately, I have never got into BOA/BOA2 although I have certainly tried.
After deciding to give it another try and reading online about the subject I came across quite a few free books that can be downloaded in various formats:

I am sure there are a lot more on this site if you search
I hope someone finds them useful...certainly some interesting stuff
regards
