Matthew Smith seizes Sarah Lloyd and her family as prisoners on a clear autumn day. Leading a party of British deserters, he now holds the family hostage north of Saratoga, New York. The Americans have just won a decisive battle, the turning point in their revolution, but Matthew's turning point is yet to come. On another battlefield in Pennsylvania, the Lloyd's oldest son struggles to find meaning in this war, while his twin sister remains trapped inside the British-occupied, rebel-capital of Philadelphia. The fate of each one of these people will be forged together that brutal winter of 1777.
