One summer's day when I was nine or ten I walked into the children's book room of the small public library in my small midwestern town. The children's room was in the oldest part of the library, which used to be a single-family Victorian house, and in spite of renovation the space still felt homey in a way I couldn't express. A shaft of light streamed in through a high window, catching motes of dust and falling on an old wingback chair. There was no one else there—my town had a dearth of readers, at least of my age. On top of a shelf was displayed a copy of James and the Giant Peach; the original edition with the real illustrations by Nancy Ekholm Burkert. This was a book of whose existence I was aware (from lists in Roald Dahl's other books) but which I had never read. I took the book to the chair and leafed through it and for just a moment, Burkert's luminous, gauzy illustrations coupled with the sunbeam and I had a sensation of flight and of being unmoored in time. I was entirely alone, and I sat there, a long while, until my mother came looking for me.
Ever since, I have chased after that emotion, whatever it was. I haven't found it, but I have found other moments as profound and as hard to categorize. When I was a teenager I spent an afternoon walking through snow following rabbit tracks farther and farther out of town. When I hit a stand of trees I looked up to see a flaming sky, more red than I could imagine, as the sun hovered low between branches; it was past dinnertime, and I felt acutely aware of the earth's rotation. There have been other moments.
