I recommend "Your Money Ratios" by Charles Farrell. It's a great financial-planner-in-a-box. While he does not avoid math, it is straightforward with plenty of examples. He also does a good job building up a financial plan, starting with earning and spending, then going into major money events (houses, kids, college, retirement). He emphasizes how they are related--those are the ratios in the title.
It is geared for traditional retirement age, and earnings from median wage to about $75k. So, not necessarily in line with MMM. But I consider it a very good primer, giving you a "license to learn" upon finishing: you will better know the areas to study further, and what questions you want answered. Everyone I have loaned or referred the book to raves about it, and for different reasons, which I take as proof of the breadth of topics covered.
