“Time travel”—and its hazards—are made literal in this astonishing new novel in which a recklessly idealistic girl dares to test the perimeters of her tightly controlled (future) world and is punished by being sent back in time to a region of North America—“Wainscotia, Wisconsin”—that existed eighty years before. Cast adrift in time in this idyllic mid-western town, she is set upon a course of “rehabilitation”—but cannot resist falling in love with a fellow exile and question-ing the constrains of the Wainscotia world with results that are both devastating and liberating.
