Billionaire Heir?

Joan was raised in the small town of Grandale, in the country of Pelubia. She thought she knew her place in the world, until a twist of fate thrust her into a much bigger role. Her biological mother, Venita, is the president of Pelubia, and Joan is her only heir. But there's a problem - Joan's foster parents were involved in the death of her father, and they're the only family she's ever known. Can she choose between her mother and her foster parents, or will the conflict between them cost her everything?
