Not My Father's Son is a memoir by the wonderful actor Alan Cumming. He was invited to participate in a reality show that traces a celebrities roots, and in his case it was going to research the life and mysterious death of his maternal grandfather. At the same time, he learns that he may not be his father's biological son. These two events prompt him to recall his childhood and the extreme physical and emotional abuse from his father that terrorized and traumatized him and his brother.
The story is interesting, but the writing was not good enough. Cumming kept attempting to build suspense and would over describe the series of intense emotions he went through during the period of filming the show. This became distracting.
Even if the writing were more elegant, I don't know if there's enough here for a whole book. A long, well-structured magazine article would be perfect.
