The Confederate army has invaded Pennsylvania.

And behind the soldiers, people are disappearing.

Free Black men, women, and children are being seized, declared property, and carried south. Among them is Samuel Odell.

Still wounded from his secret mission against Stonewall Jackson, Jonah Harlan goes after him.

But rescuing Samuel means taking on Major Anson Trask, a Confederate officer who can turn a free man into property with nothing more than a ledger, a pencil, and armed men willing to enforce the lie.

With Gettysburg approaching, Jonah has one chance to stop the prisoners from vanishing into the South.

This time, he isn't hunting one man. He's fighting the machinery of slavery itself.
