Dakota Midday host Lori Walsh visited with two-time Pulitzer Prize winner T.J. Stiles at the SD Festival of Books. Stiles discusses his latest book, Custer's Trials. General George Armstrong Custer may be a popular figure, but he's not necessarily well understood. Stiles talks about Custer's explosive and often self-destructive behavior, his bigotry, and how he existed within a "frontier of time."
