My Million-Dollar Mistake: The Mad Merman King

Chloe gets a merman king, Kellen. Comments say she's the villain he'll kill once healed. She swaps him for Dolan, who stokes his jealousy. Provoked, Kellen forces his heat on her, marks her. Dolan sells them out; killers swarm. Kellen rips out his heart to save her. Chloe sees the truth. Reborn from that heart, he takes her down, tails tangled.
