The Underground Railroad (Unabridged ed)

Cora is a slave on a cotton plantation in Georgia. All the slaves lead a hellish existence, but Cora has it worse than most; she is an outcast even among her fellow Africans.

When Caesar, a slave recently arrived from Virginia, tells her about the Underground Railroad, they take the perilous decision to escape to the North, embarking on a harrowing flight, state by state, seeking true freedom.
