All Harriet Szasz has ever known is life onstage with her sister, Josie. As "The Sisters Sweet," they pose as conjoined twins in a vaudeville act conceived of by their parents, who were once themselves theatrical stars. But after Josie exposes the family's fraud and runs away to Hollywood, Harriet must learn to live out of the spotlight - and her sister's shadow. Harriet tentatively forms her first relationships outside her family and begins to imagine a life for herself beyond the role of dutiful daughter that she has played for so long. Finally, Harriet must decide whether to honor her mother, her father, or the self she's only beginning to get to know.
