This is 3.5 stars, and I can't decide whether it should be 3 or 4 stars. I might even change it after a while. There were portions that I thoroughly enjoyed. There were portions that were thoroughly painful. Painful because, though I knew the history of Texas, including the theft and racism against the Tejanos, I hadn't spent so much time in it. I felt I was witnessing this difficult history in great detail. These are the portions of the book that deserve 4 stars.
But there is a lot of detail. I mean, you'll be off on tangents about so and so's cousin, lists of birds, etc. Maybe that's par for the genre, but still.
