There are some good kindle chess books on free promo today:
Lisa, A Chess Novel by Gradnmaster Jesse Krai is on free promo right now. You can check it out here: http://www.amazon.com/Lisa-A-Chess-Novel-ebook/dp/B00FW63QKS
I have not read it myself yet, but have seen some good publicity about it.
One book I did read, and really enjoyed, which is also on a free promo today is Chess Stories: What one Master’s Experiences tell us about Life and Work (Chess is Fun) by Jon Edwards.
This book has a lot of great little chess stories in it, and was a very enjoyable read. Very easy to read, with small chapters, and quick, bite size nuggets of wisdom the author acquired over a lifetime of playing chess.
