The story
Chosen as a bargaining chip, ordered to marry one of two orc princes.
After her father's sudden death, Charlotte is abused by her succubus stepmother and stepsisters, until a magical goblin at an elven banquet chooses her and carries her off to the orc castle. She is told to pick one of two princes and marry him at her eighteenth birthday: Vesper, an aloof snake prince, and Claude, a sunlit lion prince. As her stepsisters torment her at their supernatural academy, both princes turn fiercely protective and declare her theirs in front of the whole school. Torn between them, Charlotte falls for both, and awakens a rare and supreme bloodline of her own.
