If you are know the stories concerning selkies, seal wives, you know the issue of the skin being stolen by the husband, who then takes the woman as his wife, which, of course, was his plan from the start.
Field takes that story and not only updates but makes the center couple two guys. It is a rather good take and riff on the selkie story. The motivations of both men are well done and the story feels organic. I enjoyed it far more than I thought I would.
