Reverend John Rankin is credited with providing safety through the Underground Railroad to more than 2,000 people as they tried to escape slavery. Not as well-known as Harriet Tubman's story to most readers, Beacon to Freedom recounts in an illlustrated, nonfiction narrative how Rankin guided runaways across the wide Ohio River with a light in his window, giving them hope in a time of great fear and danger.
