Triss Crescent wakes up after being pulled from a pond, and there's something very wrong with her. Her memories feel as if they are not her own, and it takes a few minutes for her to remember her mother and father at all. And her younger sister, Pen, has an instant reaction upon seeing Triss - she screams that Triss is not Triss, and refuses to be near her.
