A fractured man and his fractured sister–that’s the central storyline in TK. Eddy and Em share a bad history. How bad? You’ll have to read the book to find out. That history has left them psychologically “fractured”–defensive, paranoid, sensitive, yearning and extremely dependent upon one another. Neurotic and maybe borderline psychotic. A prof once told me the difference: The neurotic person builds a dream castle in the sky, and the psychotic person lives in one. I always appreciated that explanation. Maybe Eddy and Em just rent one from time to time.
