Nora Eldridge, an elementary school teacher in Cambridge, Massachusetts, long ago abandoned her dream to be a successful artist. Instead she has become the "woman upstairs," a reliable friend and tidy neighbor always on the fringe of others' achievements. Then into her classroom walks Reza Shahid, a child who enchants as if from a fairy tale, and Nora is drawn into the complex world of his glamorous and cosmopolitan family. As happiness explodes her boundaries, Nora discovers in herself an unprecedented ferocity that puts her sense of self at stake.
