Let Me Ruin You, Cinderella

Ella works as a servant under her cruel stepmother until a one-night enchantment sends her to the royal ball. There Crown Prince Cassian draws her into a locked room and murmurs, "Let me ruin you." She escapes at the stroke of midnight, but he tracks her down, takes her to the palace, and locks shackles around her wrists. Before she can recover, a rival sets a trap that pins her stepsisters' murder on her, leaving the man who swore to ruin her as the only person who can save her.
