There are two first-time free paleo books today:
This first one has been around for a year. Lots of reviews. It isn't
much of a book:
The Paleo Solution or Wheat Belly? A quick comparison between two
books on eating paleo with a wheat-and-gluten-free diet (99-CENT
REVIEWS) by Michael Anderson

Paleo Lifestyle Magazine Interviews - Issue #2 - September 2012 by
Paleo Lifestyle Magazine

This author stuck paleo in as a tag. This is becoming more common.
Author's want their books to appear in as many searches as possible.
And Amazon allows this. I checked it. It is not at all paleo. I will
write a review.
