free copy of Thomas L. Friedman's
Hot, Flat, and Crowded: Why We Need a Green Revolution--and How It Can Renew America, from
Mary-Hardin-Baylor University's website.
The ebook is on the subject of environmentalism.
The book was a bestseller (somewhere, at some time). Ratings for the book now are good.
Anyway, this edition has 452 pages. There were apparently several "releases," editions,
et al. of this book that were published. I wasn't able to ascertain where along the line this edition falls.
About all that I could ascertain, of that sort of information, is that the copyright date is 2008. That makes the book a little bit dated; for example, "fracking" had not started yet then, or was just beginning to be used.
A 2009 Kindle edition is $9.99.
For you PDF-haters, I regret to tell you that that appears to be the only format available for this deal.
