Niamh's rookery doesn't approve of Feliz. He's human, not selkie, and Niamh is always giving him her fur for safekeeping. It doesn't matter that Feliz has never tried to take or hide it, just that Niamh trusts him, a human, to guard it. Feliz doesn't mind the rookery's scorn so much, as long as he can be with Niamh. But then Niamh's cousin, Flannán, decides on a surprise visit to his home, and everything changes.
