When Amelia walks in on her fiancé and best friend, her world of love and design collapses. Heartbroken and homeless, she encounters a devastatingly handsome stranger who offers a solution: a marriage of convenience. With her mother’s health failing and her trust in ruins, Amelia signs the contract, seeing only a financial lifeline. Her new husband is kind, mysterious, and oddly perfect—but he insists on keeping his identity a secret. As their platonic arrangement blossoms into real warmth and dizzying attraction, the truth explodes into their lives: her “substitute groom” is Alexander Thorne, a reclusive billionaire whose empire dwarfs her ex’s, and whose hidden connection to her past is about to rewrite her entire future.
