Book excerpt: Winner of the Governor General's Award for Fiction. Peter Behrens's bestselling novel is gorgeously written, Homeric in scope, and haunting in its depiction of a young man's perilous journey from innocence to experience. The Law of Dreams follows Fergus O'Brien from Ireland to Liverpool and Wales during the Great Potato Famine of 1847, and then beyond -- to a harrowing Atlantic crossing to Montreal. On the way, Fergus loses his family, discovers a teeming world beyond the hill farm where he was born, and experiences three great loves.
