I was a major member of the team that created this book as a weekly online serial, and am delighted that it's now available in ebook formats as well as paperback.
Whatever you think this book is by looking at the cover, you will almost certainly be wildly underestimating. This is a book that's appealled to fans of Tom Robbins, Christopher Moore, "Hitchhikers Guide", and archeological cheesecake. Bits of wisdom, romance, erotica, new-age sendups, and political intrigue/satire (2012 is an election year in Mexico and USA, let's not forget) but mostly just some hot, way-cool, kick-butt babes blasting around trying to get to the bottom of what you have when you reach the end of time.
I'd invite you to take a look at the site, including the array of videos and massive collection of pre-existing Mayan Calendar Girl art. Don't miss the Popul Voh videos of the Mayan creation myth--they are beautiful and innovative.
Available on amazon and Kindle, but I kind of reccoment the SmashWords versions for epub, mobi, etc. Cheap, high-quality, and of course any given format is available.
