Showing The Woman Upstairs by Claire Messud

Nora Eldridge has always been a good girl: a good daughter, colleague, friend, employee. She teaches at an elementary school where the children and the parents adore her; but her real passion is her art, which she makes alone, unseen.

One day Reza Shahid appears in her classroom: eight years old, a perfect, beautiful boy. Reza's father has a fellowship at Harvard and his mother is a glamorous and successful installation artist. Nora is admitted into their charmed circle, and everything is transformed. Or so she believes. Liberation from her old life is not quite what it seems, and she is about to suffer a betrayal more monstrous than anything she could have imagined.
