Myna's a selkie, though she doesn't know it. With her firstborn pronounced dead and taken before Myna can see her, it takes the birth of a second daughter, years later, to begin to mend Myna's broken heart. But then her firstborn returns, and shares the truth about Myna's past. Myna has a choice; retrieve her skin and return to the ocean-to the family she never knew and the daughter she's long grieved for, or remain on land with the husband she loves, and the daughter who can never enter the sea.
