Not Our Kind by Kitty Zeldis

In 1947, an accident between two cabs brings Eleanor Moskowitz into the world of Patricia Bellamy and her family. Eleanor is Jewish and has just left a position at a prestigious school in Manhattan when Patricia offers her a job teaching her daughter, Margaux. Margaux had polio, has trouble walking and has been very reluctant to go back to school, hence the tutor. Margaux takes an immediate shine to Eleanor, but in the upper class New York society, Eleanor is encouraged to keep her religion a secret. Things get even more complicated when Eleanor falls for Patricia's older brother, Tom, and Patricia's husband, Wynn, becomes increasingly angry about Eleanor's presence. Told through the eyes of Eleanor and Patricia, Not Our Kind explores the two women's very different lives in a time of change.
