Swing low, sweet Harriet

There are tales among the slaves on the Lowndes plantation of a woman known as Moses leading folks to safety and freedom. When she begins showing up at their meetings sharing the message of "Be ready. Freedom is at hand," some are curious to know more, while others think it's safer to keep a distance from her. Can she be trusted? Ben knows a dangerous secret and must decide whether to share what he knows with this mysterious stranger.
