A portrait of an enduring friendship, from one of America's most celebrated novelists. Two priests are despatched from Rome to New Mexico to reinvigorate Catholicism among the locals, knowing little of the challenges that await them. Over almost four decades they encounter a rich variety of people, from rebellious Mexican priests to steadfast Native Americans uninterested in changing their longstanding customs. 'Its whole effect works slowly and mysteriously ... a major, and rare, artistic achievement' AS Byatt
