This is definitely a good book if you really need to get a hold of your finances. Don't be fooled, though: it takes a lot of commitment. I started doing the steps and then stopped half way through. However, I am determined to go back and do it properly. The authors are honest with you: if you don't have the commitment it won't work. This includes doing things like tracking every penny you spend for a few months. Yes, every penny. VERY boring for a carefree, numbers hating, lets-go-and-have-fun-instead person like me, but necessary if you really want to see change.
If you are anything like me (enough money, not in massive debt but can't be bothered to open bank statements so whoops, I'm in my overdraft again and hmm, where did that payrise go..?) then you probably know that you need to change your behaviour. This book does a good job of giving you the tools to do it...whether you follow them is up to you.
So, this is not a get rich quick thing. It's about understanding how you relate to money and addresses fundamental issues of the way we live today.
Buy it: it's good!
