"I am leaving you all my journals, but you must promise me you won't look at them until after I'm gone." This is what Terry Tempest Williams's mother, the matriarch of a large Mormon clan in northern Utah, told her a week before she died. It was a shock to Williams to discover that her mother had kept journals. But not as much of a shock as it was to discover that the three shelves of journals were all blank. In fifty-four short chapters, Williams recounts memories of her mother, ponders her own faith, and contemplates the notion of absence and presence art and in our world.
