Seven years ago, Quinn finally dared to transform from a seal into a human and took her first steps on land. As a selkie, she is both a daughter of land and sea. But when a human stole her pelt, he stole her freedom as well, forcing Quinn to become his wife and bear his children. As legend tells, capturing a selkie will bring you luck, and she became a coveted prize.

Constrained to a life that was no longer her own, Quinn longed for nothing more than to find her pelt and seize her freedom. Then one day, her eldest daughter hands Quinn her pelt and without a second thought, Quinn snatches it and escapes to the sea. But she's no longer used to swimming and doesn't know where her herd has gone. And after an almost disastrous encounter with her former husband, leaving her severely injured, Quinn doesn't even have the strength to go searching.

Instead, she finds herself taking shelter on a nearby island with a lighthouse and three lighthouse keepers. Quinn doesn't trust humans anymore and wants to stay hidden from the keepers. But she can't survive on her own either. Can she learn to trust these humans and shed her hatred of all humankind? Or will she give into her fears and accept the monstrous fate that others have bestowed upon her?
