Summary from GoodReads: Duncan Campbell is a natural born leader, possessing all the attributes for a Highland chieftain except for one: legitimacy. Forced from the Highlands for a crime he didn’t commit, Duncan has earned a reputation as the fiercest, most skilled mercenary on the continent. Vowing to restore his name and clear the cloud of treason hanging over his head, Duncan returns to the Highlands to find the one person who might hold the key to his freedom: the woman he’d once loved who’d betrayed him. But when he surprises her swimming in a loch, he finds himself facing the bad end of a pistol.
Told she was impulsive her whole life like her mother who’d destroyed their family when she’d run off with an Englishman over twenty years ago, Jeannie Grant had never believed it—until she met Duncan Campbell. The bastard born son of a chieftain was not a suitable husband for the daughter of a powerful Highland chief, but Duncan made Jeannie willing to risk everything. She gave him her innocence and he failed her, forcing Jeannie to learn the hard way what happens when you follow your heart. Now Jeannie is shocked to find that the brigand she’s shot is the same man who broke her heart all those years ago. But the hard, ruthless man is nothing like the charming young scoundrel she remembers. When their attempt to prove Duncan’s innocence uncovers a deadly secret, not only their lost love, but their lives hang in the balance.
