While Rivers Run by Maurice Walsh

This highland tale of fishing and romance focuses on Alistair, a young American laird, and his cousin Don. When they fight over Norray, an actress who has bewitched both young gentlemen, Alistair is left battered. Aleac, an occasional poacher, finds the laird and brings him home to be nursed back to health. There, he meets Aleac's niece Margaret...and the action really begins.
