My Captive Siren Wants a Baby

PhD student Jonah travels to Emerald Island to study merfolk, and to rescue a stalled dissertation mistakes a dangerous male siren for a clueless merman, teaching him to sing and dance. When the advisor warns that sirens abduct their mates rather than court them, Jonah flees, only to be caught by Ash and locked in an underwater cave. Ash insists Jonah promised to return more than ten years ago, a memory Jonah lost after a high fever. As the past slowly surfaces, Jonah must face Ash's deep distrust of humans and his plan to send Jonah away while carrying a child.
