Amazon is currently offering the e-book Organized Simplicity for free. I have heard fantastic things about this book by Tsh Oxenreider and just started reading One Bite at a Time which is also written by her. I have included these books in my tool kit to help me get organized in 2012 and aid me with my ongoing self-discipline and accountability goals.
The price is currently $0, but could increase at any time. Please be sure to check the price before you buy the book.
