Lucky me!! I've found yet another resource for free Kindle e-books! This is a Facebook page that posts throughout the day. Not all of them are free, they do post a few greatly reduced titles. Pay close attention to the Amazon page to make sure you're getting the free ones.
Log on to Facebook and go to Ebook Deal of the Day. "Like" the page. After you've completed that, hover over the "Liked" button until the drop down menu appears. Make sure to check the "Show in News Feed" option. This way, the posts for free books will appear in your news feed and you won't have to hunt them down.
Load up your Kindle, make a cup of peppermint tea, and begin your voyage to other times and places!
