Despite Honoré de Balzac's title, these aren't memoirs; rather, this is an epistolary novel. For some ten years, these two will--enthusiastically if not always faithfully--keep up their correspondence, obeying their vow to tell each other every tiny detail of their strange new lives, comparing their destinies, defending and sometimes bemoaning their choices, detailing the many changes, personal and social, that they undergo. As Balzac writes, "Renée is reason...Louise is wildness...and both will lose." Balzac being Balzac, he seems to argue for the virtues of one of these lives over the other; but Balzac being Balzac, that argument remains profoundly ambiguous. "I would," he once wrote, "rather be killed by Louise than live a long life with Renée."
