In 1783, three-year-old Sarah Whitcher (the authors' great- great-great-great-great-aunt) wandered into the woods near Warren, New Hampshire; four days later, she was found by a man who had dreamed that she under a particular pine, guarded by a bear. Some of the searchers—who found Sarah surrounded by bear tracks—recorded this experience, as did Sarah herself, years later. Alternating between Sarah's journey (unafraid of the endearingly gentle animal because she thinks it's a ``big black dog,'' she curls up next to it and goes to sleep) and the family and neighbors' search, the authors re-create the incident in a simple, direct narrative enlivened with dialogue and authentic detail. Rand's settings—especially the darkening forest, in luminous shades of gray-green, and the soft, furry bear—are beautifully painted; his humans are a bit trite and over-pretty, but that's a small flaw in an unusually appealing slice of Americana.
