The Maid Is the King's Lost Queen

Maid Selena, tormented by rival Daphne, meets PTSD-stricken underground king Lucian—her scent soothes his rages. Her moon pendant reveals her as the slain royal syndicate’s last heir. She marries Lucian for revenge, unlocks royal blood, uncovers a 30-year massacre scheme, defeats foes, avenges her clan and rules the dark empire with him.
