The first book I'll offer up is Mary Hunt's Debt-Proof Living. This is one of the first get-out-of-debt books I ever read, and it had a tremendous impact on me. My Freedom Account page is based on what I read in Debt-Proof Living, as well as is my Rapid Debt Repayment Plan page. The fact that DPL resides on my Money Reading List should tell you that I think pretty highly of it. If you're in the middle of a debt paydown, or if the Little Voice in Your Head is telling you that you should be working on one, then you won't find better reading material than Debt-Proof Living.
This is the 1999 edition of DPL. It's in great condition, with only a couple of handwritten URLs written on a page in the middle of the book. I'll send it to the first respondent who emails me at ...
... to let me know he/she wants the book. I'll ask only for $3.50 to cover shipping and Paypal fees (if paid by Paypal), or $3 if paid by Google Checkout.
UPDATE: As of May 5, the book is given away (pending payment).
