As the Revolutionary War rages on, Isabel and Curzon have narrowly escaped Valley Forge--but their relief is short-lived. Before long they are reported as runaways, and the awful Bellingham is determined to track them down. With purpose and faith, Isabel and Curzon march on, fiercely determined to find Isabel's little sister Ruth, who is enslaved in a Southern state--where bounty hunters are thick as flies.

Heroism and heartbreak pave their path, but Isabel and Curzon won't stop until they reach Ruth, and then freedom, in this grand finale to the acclaimed New York Times bestselling trilogy from Laurie Halse Anderson.
