The Sweetest Substitute, Forever His Only One

Rhea Roth spends her early years in poverty after being switched at birth, and at nineteen she is finally taken back into the family that raised someone else in her place. Adjusting to a world of wealth and expectation is hard enough, but Rhea also finds herself tangled with a billionaire whose life is bound up with hers in ways neither of them expected. Old loyalties, a marriage that has grown cold, and the question of where she truly belongs push her to decide what she wants from the people now claiming her.
