The Ghost Writer - Philip Roth

This is one of Roth's earliest novels, and as accomplished as you would expect. In a shortish span, it delves into the identities we construct for ourselves and for others, the responsibilities of the artist and Jewish history. It's also the first of the Zuckerman books and what an unreliable narrator he turns out to be, to the extent that by the end the reader is left wondering which aspects of the story have been "real".
