Where can a person find good books for under $5.00?  On amazon.com of course.  Check these out for yourself.  http://www.amazon.com/Mary-M.-Hall-Rayford/e/B00BAW31CQ.  When you read (mine or others), please review on Amazon.  We really want to know your thoughts; especially if it includes telling us how we can improve our production of literature.
