Who is Enric Marco? An old man from Barcelona who claims to be a Nazi concentration camp survivor and rises to be president of Spain's leading Holocaust survivor movement, the Friends of Mauthausen. And who was unmasked as a fraud in Austria in 2005. This is an extraordinary novel that not only tells Marco's self-deluding story, but also challenges the reader to consider how truthful any of us is in the way we present ourselves in daily life. Are we not all, asks Cercas, the novelists of our own lives?
