Diana Gabaldon, the #1 New York Times bestselling author of the Outlander saga, brings back one of her most compelling characters: Lord John Grey. Here Gabaldon weaves together the strands of Lord John’s secret and public lives-a shattering family mystery, a love affair with potentially disastrous consequences, and a war that stretches from the Old World to the New. It’s been seventeen years since Lord John’s father, the Duke of Pardloe, was found dead, a pistol in his hand and accusations of his role as a Jacobite agent staining forever a family’s honor. Now unlaid ghosts from the past are stirring. Lord John’s brother has mysteriously received a page of their late father’s missing diary-and John is convinced that someone is taunting the Grey family with secrets from the grave. So he turns to the only man he can trust: the Scottish Jacobite James Fraser. But war, a forbidden affair, and Fraser’s own secrets will complicate Lord John’s quest-until James Fraser yields the missing piece of an astounding puzzle and Lord John must decide whether his family’s honor is worth his life.
