Alladar

A family of three are yachting in the Caribbean during Christmas. Their boat catches fire and after a storm they find themselves stranded on an island along with a sailor from their ship. Three men - a husband, a son, and a young sailor - are left alone with a single woman. It doesn't bode well for her. First story will be written from the POV of the son, who can be a good boy and help his father for no reward, side with his father against the outsider sailor and then turn on him, side with a sailor against his father and share mother, or play them against each other and stay the last man alive. Or to lose and die. Don't forget, you are still stuck on the desert island, and the winter storms are coming. Sex and social games are good, but food supply and durable roof over your head is probably better.
