Please note: The price on all 3 is currently $0, but please make sure to double check the price before checking out. I believe the offer ends after today.
If you don't have a Kindle (I don't!), you can download a free reader from Amazon for your computer or smart phone.
I haven't personally read these books, but have been wanting to for quite awhile, so I was pretty excited to see them for free!
