UPDATED:Tuesday morning, Dec. 18. The Couples Money book mentioned in the post is no longer offered for free. It is $9.99 or free if you have Amazon Prime Membership.
Here is a link for some of the Kindle ebooks that are free right now. Double check the pricce before ordering, since the price can change at anytime. There is one about personal finance for kids and another on Couples and Money.
Even if you don’t have a Kindle you can download a program to read Kindle ebooks on your computer, tabliet and some mobile phones.
