It's easier just to point you to a list of my favorite finance books on my site rather than copy the list here.

I'm not a very big fan of Rich Dad stuff since it lacks the specifics. I suppose it's great that it helped a lot of people start thinking about money, so in that regard it's a good book. But once I got over that, I wanted some books with a little more substance. A great finance book is The Truth about Money 3rd Edition by Ric Edelman.
