Who is Florrie Peace from The Truest Pleasure and what is their importance?

Florrie Peace is Ginny's older sister. She is described as tall, beautiful, flirtatious, and funny. Everywhere she goes, attention follows her. Florrie is the only member of the Peace family that does not believe in the power of Pentecostal revivals, and her faith in general is questioned throughout the novel. This ambiguity of religion draws Florrie and Tom together to form a bond outside of his bond with his wife, Ginny. When this happens, all of Ginny's teenage insecurities come back when she questions whether or not Tom believes he married the wrong sister.
