Book recommendation?

[Rvrrat]

Thanks everyone, for the suggestions. I know that there is an unimaginable number of books out there on the subject. Having y'alls' suggestions will definitely help me narrow it down a bit. Although after I get a book for my father, I'll undoubtedly be picking up a couple of these to read myself. This is one of the things that makes this a great place. Most of y'all are so quick to help out another. I hope I can pay it back in the future. Thanks again!
