“WISH YOU WERE HERE.” By Graham Swift. Knopf. $25.
“A good novel,” Graham Swift wrote in a recent essay in the New York Times Book Review, “is like a welcome pause in the flow of our existence; a great novel is forever revisitable. Novels can linger with us long after we’ve read them — even, and perhaps particularly, novels that compel us to read them, all other concerns forgotten, in a single intense sitting.”
