Autumn, 1707. Old enemies from the Highlands to the Borders are finding common ground as they join to protest the new Union with England, the French are preparing to launch an invasion to carry the young exiled Jacobite king back to Scotland to reclaim his throne, and, in Edinburgh, the streets are filled with discontent and danger. When a young widow, Lily Aitcheson, comes forward to collect her lost husband's wages, former soldier Adam Williamson is assigned to investigate her petition and the veracity of her claim. As Lily tells her story, Adam has only days to discover if she's being honest, or if his own feelings are making him blind to the truth. But sinister figures lurk in the background—is Adam being used as a pawn in an increasingly treacherous game?
