Today, we visit with Saint Mark's member Tom Zoellner, whose latest book, "Island on Fire" is a dramatic day-by-day account of the uprising of enslaved people led by Baptist minister Samuel Sharpe in December, 1831. A signal event in the 19th Century, it has been largely forgotten, but Tom explains how its repercussions influenced 20th Century resistance movements, and are relevant to today's Black Lives Matter movement.
