It took me 3 months to finish this book, but I pretty much figured that going in. Anyone expecting a book laid out prettily for people in some sort of story-like format shouldn't pick up this book. It can be dry in the sense a history book is dry. It's one of the history books we should all be getting taught as Americans, but don't.
For the most part, I picked up this book to get more depth on a topic I already knew a good bit about. In addition, it was to expand my knowledge out of Texas, which I know the most about, to the rest of the former-Mexico-now-the-U.S. Southwest. Also, I was interested in a book covering the then-too-taboo subject of Black ancestry in some of our families. As others have noted, unfortunately in this book there wasn't a lot of that or at least not as much as many are used to reading, focusing instead on Indigenous ancestry and only glancingly mentioning the other group. Unfortunately, that's what almost always happens to Mexican Americans in books and articles.
It was a "great" to learn so many of the varied ways that Spaniards and Anglos found to terrorize and steal from Indigenous and multiracial people. That's part of why it took me so long to make it through because a lot of the time I was only reading 10 pages at a time before I had to put the book down and digest and/or not be tempted to throw the book at the wall. Angering and sad how so many people were harmed. Most of the specifics in how Spaniards went about things was new to me, though, in particular that the Church actually protected (in their twisted way) land for Indigenous people. Then, at one point near the end of the book I felt like I was making it through all the begats in the bible or reading "The Silmarillion" (for the Tolkien fans) when it came to a section talking about all the land theft first after Anglos took over Texas and then again when the U.S. took the Southwest/made the Gadsden purchase. Just as I did a little skimming because it was the same over and over, it was over, so thankfully I skimmed very little.
Finally, the book interestingly closes with a personal connection to all of this history, showing how it effected people in their family. It showed how in so many instances some history may be hard to recover or fully know because the people it involves had to go underground, if you will, and the actual ancestry may be lost forever because of the real-world consequences not to mention the stigma of being from an oppressed group. Ethnic identities are often based on feelings rather than "fact" at the end of the day.
Highly recommended for Americans who should learn more about the U.S. history of the largest ethnic minority group in the country.
