Book excerpt: William Trevor's Last Stories is forthcoming from Viking. In Reading Turgenev, which was shortlisted for the Booker Prize, an Irish country girl is trapped in a loveless marriage with an older man, but finds release through secret meetings with a man who shares her passion for Russian novels. My House in Umbra tells of Emily Delahunty, a writer of romantic novels, who helps survivors of a bomb attack on a train to convalesce, inventing colorful pasts for her patients. Two novels, two women who retreat further into the realm of the imagination until the boundaries between what is real and what is not become blurred.
