Yes, I bought and read it last month, and agree that it is well done. Karen does a great job of taking complex matters and making them simple. I noticed also that it is one of the few books which also addresses some of the common myths perpetrated on the internet. A refreshing read, to say the least.
If you ever get a chance to see Karen speak at a local club, I highly recommend it. Her presentation(s) are also outstanding.
