The Fiery Cross by Diana Gabaldon

The year is 1771, and war is coming. Jamie Fraser’s wife tells him so. Little as he wishes to, he must believe it, for hers is a gift of dreadful prophecy—a time-traveler’s certain knowledge. Claire’s unique view of the future has brought him both danger and deliverance in the past; her knowledge of the oncoming revolution is a flickering torch that may light his way through the perilous years ahead—or ignite a conflagration that will leave their lives in ashes.
