I very much encourage everyone to read or listen to this book. Follow the author to important heritage sites to the legacy of slavery through the US and beyond; plantations, prisons, confederate cemeteries.  Made me very reflective on random interactions I have had over the years and how the people in my family history may have interacted. The content is graphic and unflinching, which is entirely necessary. It is also one of the best written non-fiction books I have read, I believe because you are going on a journey with the author. I am unable to summarize so much of one amazing book, so I am just going to say again read it.
