The story's two main protagonists are Jean Luharich and Carlton Davits. Luharich is a successful businesswoman and media celebrity who is financing, and commanding, an expedition to capture an Ikky. Davits is a work-for-hire seaman who has been on the crew of several earlier attempts, and in fact had once been in Luharich's position: a playboy sportsman who commissioned the ship Luharich now owns, until he was injured in a disastrous try whose failure he blames himself for. Davits and Luharich were previously involved in a brief romantic relationship which ended years before the story begins.
