There is one first-time free paleo book today:
The Paleo Lunch For The Working Woman Easy And Delicious Paleo
Recipes Volume 1 by Jessica Andrew
http://www.amazon.com/dp/B00A46DS0Y
This is the second in this series to go free. I reviewed the first
and found that all the recipes were taken from the web. I will write
a similar review for this in a couple hours. Since it is free, you
may still want to have the recipes conveniently in a Kindle book form.
These are free again today:
