Oh geez. Shocking, not that these evil has existed, but the depths of the evil. Grann tells the story with no holds barred. I appreciate his detail and storytelling and clear care and sorrow for the Osage people. The Reign of Terror is an important piece of American history, and I would recommend this to anyone curious about understanding what the Osage have been put through. If you struggle with non-fiction this also doesn’t have that textbook-y read to it, without watering down the info.
