What it's about

Dominick Birdsey has spent his life looking after his identical twin, Thomas, who has paranoid schizophrenia. In 1990, Thomas walks into a public library and commits a shocking act of self-harm, believing it's a sacrifice for peace. As Dominick fights to get his brother out of a maximum-security hospital, he also has to face his own anger, his failed marriage, the mysteries of his family's past, and the manuscript left by his Sicilian grandfather.
