I just finished The False Cause: Fraud, Fabrication, and White Supremacy in Confederate Memory by Adam Domby. It's from a history professor that I actually knew when I lived in North Carolina. He was going to grad school at UNC Chapel Hill with my girlfriend at the time, so it's kind of cool to see his book published and recognize a lot of the names in the Acknowledgement section. Also he has been in the Washington Post, New York Times, CNN, etc. on the issue of Confederate memory, especially lately given how often Confederate monuments are appearing in the news.
Anyway, the book was really interesting and timely, too. It examines the myth of the Lost Cause and how the attempt to recast the loss of the Civil War by the Confederacy was really an attempt to support white supremacy. That this was done is probably not news to anyone paying attention, but exactly how and why this was done is the focus of the book. Essentially, it boils down to the South portraying itself as a homogeneously white and supportive entity, when in fact the Confederacy had far more issues than the US with deserters, dissenters, pension fraud after the war, etc. The book really tears apart a lot of neo-Confederate arguments, too, so that's pretty satisfying if you hear people saying things like "it wasn't about slavery" or they try to glorify the Confederacy or Confederate soldiers. The book is also a really interesting look at how historical narratives are created and maintained.
I know we have a couple people who are interested in history ( @Emperor Diocletian II and @CastlevaniaNut18 come immediately to mind) though I don't remember whether there's much interest in Civil War history. In any case, as a former history minor, I loved the book and I'd definitely recommend it.
