Please do not try to purchase the book at this time. It appears that the link to buy the book online is working, but it is not. I will try to have this resolved ASAP. The problem is that the company who hosts the merchant account and processes the credit cards misrepresented their services, so I need my webdesigner to add another page or two to make it all work. I'm sorry for the inconvenience. If you have made a purchase already, the transaction will be voided and you will be sent an email indicating this. Thank you.
