The beloved star of stage and screen, Alan Cumming's life and career were shaped by a complex and close family past full of disturbing memories that were kept secret. But then an unexpected phone call from his long-separated father brought the pain of the past back to the present and destroyed everything he thought he knew about himself. Not My father's Son is the story of his journey to discovery, at the same time a memoir about his childhood in Scotland and a study of his family history that will change him forever.
