The Selkie Death

Fiona is a dutiful selkie and has spent her life adhering to her father's strict rules.
One night, she breaks when she's carried to shore by the relentless waves. Shedding her selkie skin, she stumbles into the human world. Little did she know that her decision to break the taboo would set into motion a chain of events that would unlock a tale of forbidden love, uncover the secret behind a murder, and a struggle to preserve the delicate balance between two worlds.

PS, Real selkies either stay in full seal form or human form.
