I Know This Much is True by Wally Lamb

Second Hand

The #1 New York Times bestselling novel, now a major Sky Atlantic drama starring Mark Ruffalo as two identical twins, Thomas and Dominick.

Dominick Birdsey's whole existence is coloured by the knowledge that his twin brother can never be fully responsible for his frightening behaviour, while he himself has beaten the biochemical odds to remain sane. But at what cost?

This powerful, heartwrenching drama draws on the deepest human emotions: the need to know oneself, responsibility to family, the influence of hidden history. The result is a highly acclaimed novel of survival, written with great sensitivity.
