Erin Murphy has learned to expect the unexpected in her family, but she never expected to find herself dead. As the nanny for a wealthy couple, she accompanies them as they set sail on their family vacation. While sun is the enemy of her Irish skin, she plans to enjoy the next two weeks without her eccentric uncle and impossible security guard. After a body is found at the marina, those plans quickly get derailed as she suspects there is more to the murder than meets the eye.
