Malcolm MacLaren has come to the small Scottish island of St. Columba for one reason—revenge. He hasn't counted on a beautiful, fairy-like widow to haunt his footsteps, a woman so irresistible that he could almost forget his reason for being there.

Ailie Spens is an old soul. She dances barefoot in the moonlight, floats like a fey creature among the relatives who try to rule her life and does her best to convince everyone she is half-mazed. And she knows when a man is under an enchantment.

He walked from the sea, terrifying the townspeople, and everyone knows he must be a selkie, a man on land and a seal in the icy North Atlantic. But Ailie knows he has come for her, to rescue her from the stifling future her relatives have deemed proper.

Now she simply has to convince him to take her with him when he returns to the deep, dark sea.
