Absolutely read all the Gary Jennings books you can get your hands on. (All the ones that were actually written by him that is, as there are several that were ghostwritten which are no where near as good). Don't let the massive page count and onion skin pages deter you... This book is well worth it. Jennings has all the best aspects of good historical fiction: deeply researched, educational, but has enough trash in to keep you going. From what I understand, Jennings spent many years traveling from Mexico southwards, learning about pre-Columbian societies. The book is rich with details, not just about history, but even down to the food they ate, toys they played with, and artwork. There is also a fair amount of humor--the juxtaposition between the clever Mixtli and the supposedly more advanced conquistadores was great.
