Not My Father's Son

Not My Father's Son is a memoir I wrote about my experiences during the summer of 2010, when I took part in the BBC TV series Who Do You Think You Are?  At the same time as discovering the secrets of a family mystery about my maternal grandfather, Tommy Darling, I was also sideswiped by the revelation of my father telling me I was not his son.  

The book was released in the US in October 2014, and in the UK a month later.  It entered the New York Times Best Seller list in its first week of issue.
