By the time she gets there, he has vanished...and in his place are five mysterious men who have a strange connection to the sea. As they help her search for the missing scientist, Daq, Janko, Ivar, Ejan and Tagin introduce Maura to the uninhibited life they enjoy on the island. Before long, they ask her to join them in their balmy paradise, and she is tempted to accept. However, Maura can't help wondering about her new friends' role in Dr. Miller's disappearance. She has also begun to suspect that they aren't exactly like other men. Can she respond to their desire for her, wondering if they might not be what they seem? Should she give into what she feels for them, knowing that they might not be human?
