While I do buy my own books or borrow from friends, family, and the library, a good deal of the books that I review are ones that I have received from the publisher in exchange for an honest review. I am not being paid for my reviews. My opinions are most definitely my own. Except for the children books, where my opinions are my kids'.
Links to buy the books are affiliate links--they don't cost you anything extra, but they do pay a small amount to help pay for the cost of running this site.
