Alpha King's Cursed Captive

Cursed werewolf Ella has one night to live—unless someone marks her. Instead, she catches her fiancé cheating with her sister and jumps into a pool, accidentally freeing Alpha Derek, a chained king. His bite saves her. But when he reclaims his throne and names her Luna, her sister demands a chastity test. Ella hides his mark with a spell—passing, barely. Derek wants to mark her himself. But his curse is returning, and her secret is one wrong move from death.
