A man consumed by revenge. A woman living a lie. A forbidden love that could ruin them both. After seven years at sea, Edmund, Duke of Tavington, returns to England for vengeance. Someone murdered his best friend, nearly killed him, and stole the life he should have had. Now a woman he's never met is posing as his duchess—and raising a boy who bears his title. Ailis Tierney has survived the impossible by hiding in plain sight as Alice, Duchess of Tavington. She's rebuilt a failing estate and kept a secret that could cost her everything. But when a dangerous stranger arrives—far too perceptive, impossibly compelling—her carefully crafted world begins to fracture. Their clash ignites a tension neither can resist. Their lies bind them more tightly than truth ever could. And their shared enemy is closing in, ready to destroy them both. The Counterfeit Duchess is a story of deception, danger, and a love powerful enough to burn through every lie.
