I read this book in June 2017, and this review is expanded upon the one I initially posted on Goodreads then. 

Killers of the Flower Moon by David Grann is an excellent read about a relatively unknown subject of Oklahoma history — the murders of many Osage Native Americans, over oil rights. This was also a landmark case in the development of the FBI, and J. Edgar Hoover’s reign there.

Despite being nonfiction, this book reads more like a novel than a textbook, so if you are leery about the genre, don’t be. Grann’s intensive research is evident, but his writing style is engaging. He mostly follows the story of a particular Osage family, who are at the center of the entire case, as well as that of Hoover and the other investigators. Overall, this is a great book.

Overall rating: 8/10
