Lavinia Gibbs defies social convention and family expectations in New York in the 1930s when she breaks off a passionless engagement to a prominent banker. Instead of surrendering to an invisible spinsterhood, Lavinia moves to Paris, where, on the verge of World War II, her sexual and political awakening collide in an unforgettable tale.
