The Total Money Makeover.
He apparently is a huge, life-changing help to many people whose life is overrun by debt. And to me, this is a big deal. I look at it as your money is either working for you, earning interest and dividends, or working against you by charging interest, late payments, overdraft charges, etc. Much of the nation seems to be in the latter boat.
From time to time I run into people who spend more than they make and are digging themselves into the debt hole and recommend that they read Ramsey.
Having said all this, I cringe when he talks about investing in a "good mutual fund that earns 12%". By the rule of 72, a 12% return doubles your money every 6 years. Wow! This sounds pretty easy (especially in a world of 2% inflation and anemic bond yields) and exciting to an investment novice. Unfortunately, it is not that easy; and evidence shows that funds with prior superior performance tend to subsequently underperform the market and have high fees that severely penalize investors.
Here are two other recent takes on Dave Ramsey:
