Cosette's mother's name was Fantine, who was a factory worker. When Fantine is thrown out for having an illegitimate daughter, she becomes a prostitute. An ex-convict on the run, Jean Valjean, rescues Fantine, but alas, she cannot be saved and dies from comsumption. Valjean vows to take care of Cosette, and he rescues her from the Thenardiers, a cruel family that was raising- as well as abusing Cosette- during the first eight years of her life. For the next nine years, Cosette lives in happiness, albeit seclusion, with Jean Valjean.
