This is possibly one of the WORST books ever written on the matter, absolute dogshit, very very disrespectful to the ancient Toltecs. Barely mentions The Toltecs, which in turn were the reason why it caught my attention. For starters, the author assumes the reader is already familiar with the following historical accounts: "Historia Tolteca-Chichimeca" "Annales de Cuhuahututlan" "Chilam-Baalam" If you, like me, haven't heard of, let alone read and thoroughly pondered, the aforementioned texts, then don't even bother. Not only that, but I can't help but notice that the author doesn't mention anything new or gripping; the book reads as if the author jotted down notes to self while studying the previously mentioned texts. And I'm not even kidding it speaks of the Maya, Nonoalcas, Aztecs, Otomi, Zapotec and For God's sake it even mentions the Inca. Well into chapter 8, not once were the Toltecs' daily lifestyle, religious practices, pantheon, warfare, or agriculture mentioned or even proposed. Again, absolute dogshit, don't waste your time.
