For Andre Dubus, "the quotidian and the spiritual don't exist on different planes, but infuse each other. His is an unapologetically sacramental vision of life in which ordinary things participate in the miraculous, the miraculous in ordinary things. He believes in God, and talks to Him, and doesn't mince words. He believes in ghosts . . . He is open to mystery, and of all mysteries the one that interests him most is the human potential for transcendence." So wrote Tobias Wolff seven years ago, about Andre Dubus's Broken Vessels, and that insight describes perfectly the twenty-five pieces in this powerfully moving new collection, a continuation of Dubus's candid, intensely personal exploration into matters of morality, religion, and creativity. Since that first book of essays, written after the 1986 accident that cost him his leg and, for a time, the ability to write, Mr. Dubus has published Dancing After Hours, a unanimously heralded book of stories "at once harrowing and exhilarating" (Time).         Here is Dubus on the rape of his beloved sister, his first real job, a gay naval officer, Hemingway, the blessing of his first marriage, his dear friend Richard Yates, his own crippling, lost autumnal pleasures, having sons and grandsons, his first books, meeting a woman who witnessed his accident, the Catholic church, and, of course, his faith.         A writer of immense sensitivity, vulnerability, and thoughtfulness--a master at the height of his talent--whose work "is suffused with grace, bathed in a kind of spiritual glow" (New York Times Book Review).
