Book excerpt: Harriet Tubman was born a slave on a Maryland plantation in the 1800's. She trusts in God, but her faith is tested at every turn. Should she obey her masters or listen to her conscience? This story from Harriet's childhood is a record of courage. Even more, it's the story of God's faithfulness as He prepares her for her adult calling to lead more than 300 people out of slavery through the Underground Railroad.
