On the beaches of Orkney, Scotland, an evil entity stalks mortal women. Machar “Mack” Kirk is a selkie man with a haunted past, one that has prompted him to become a hunter. He prowls the beaches at night, his arrows aiming for the finman who took his first love. Beth Pedersen also watches the sea. The haunted widow has suffered losses of her own, ones that have crippled her into a state of stony grief. Beth can no longer feel, can no longer see color and life. Until the day Mack Kirk saves her from a mysterious foe, flooding her world with brightness and foreign temptation. As Mack and Beth fight their inundating passion, the finman escalates his attacks. Before long, Mack realizes he’s not just playing Good Samaritan. He wants Beth, too, and will do anything to ensure his lover isn’t taken by the finman. But can he protect his mate from a monster with no soul?
