Fake Heiress, Mermaid Princess

After twenty years as a Haile, Lyla is cast aside the moment the family finds their biological daughter Serena. The room, the ring, the Morrison engagement—all revoked. At a gathering, Serena demands the ring. Lyla tosses it into the pool. Serena pushes her in.

Underwater, her legs fuse into a tail. She screams for help. No one moves. When she surfaces, gasping, the family who raised her stands frozen. A monster, they call her. Her adoptive mother hands her a severance check. Leave tonight. Never come back. Never speak of what you are.

Lyla takes refuge in a villa her late grandmother secretly left her. Alone, she tests what she has become. A drop of water raises scales. Full submersion brings the tail. Drying off reverses everything. A lifelong fear of water suddenly makes sense. Her tears, she discovers, form something else—a pearl that can reverse terminal illness.

Her adoptive mother, now dying, comes asking for one. Lyla refuses to let her skip the queue. My tears can save lives, but they are not a reward for the people who hurt me. Submit an application. Wait like everyone else. The woman who threw her away walks away with nothing.

Under Kyle's guidance, Lyla uncovers her true lineage as the mer-royal heir. She confronts the fiancé who abandoned her and the schemes of those who sought to destroy her. She chooses compassion over vengeance, using the healing pearl on critically ill strangers, transforming hatred into mercy, and protecting countless lives with the ocean's gift.
