"Forgotten voices were everywhere." A Promised Land by Barack Obama.

After escaping bondage, twenty-five-year-old William Henry Johnson goes to the nation's capital as Abraham Lincoln's valet, hoping the new president will help him reunite his family. But when Lincoln chooses an expedient peace over racial justice, the war against slavery may be doomed--unless Johnson can turn him from long-held prejudices and convince him to embrace equality. Changing Lincoln's heart and mind comes at a severe price.
