Lady Kiera Darby and her dashing husband, Sebastian Gage, hope they've finally found peace after a tumultuous summer, but long-buried family secrets soon threaten to unravel their lives . . . October 1832. Kiera is enjoying the slower pace of the English countryside. She, Sebastian, and their infant daughter have accompanied her father-in-law, Lord Gage, home so that he can recuperate from the injuries he sustained in a foiled attempt on his life. But as the chill of autumn sweeps across the land, they receive a summons from an unexpected quarter. Lord Gage's estranged uncle--a member of the notorious Roscarrock family--has been murdered, and his family is desperate for answers. Despite Lord Gage's protests, Kiera and Sebastian press on to Cornwall to assist. It isn't long before they discover that almost nothing is as it seems among the Roscarrocks, and they've been lured to their isolated cove under false pretenses. There are whispers of a lost treasure and frightening allusions to a series of murders stretching back decades that touch the lives of the family personally. Kiera and Sebastian are left with no choice but to uncover the truth before the secrets of the past threaten to destroy them all.
