Skin

When seventeen-year-old Ocean O'Malley's family moves to the windswept shores of Prince Edward Island, she discovers more than just beaches and a mysterious hot neighbor named Sam. Sure, there’s the usual new-girl-in-a-small-town stuff—near kidnappings on the beach, popular girl hate-pranks and gym class bullying. And even a painkiller-induced hallucination where she may or may not have seen Sam turn into a seal. Seriously. Grown, questionably naked hotties do NOT just turn into seals.
But when Sam lets her in on his secret, she discovers that something of hers is missing. Something she didn't even know existed. Her mother has lied about it and years ago her father disappeared with it. Sam’s father wants it—is willing to kill for it. And only when she first slips beneath the salty waves with Sam does she truly discover what that something is.
Her skin.

This young adult paranormal is similar to an underwater HUSH HUSH, set on the northern Atlantic coastline. It introduces a selkie world of magic and intrigue, and is a beach read with a dark twist.
