Nana is a novel by the French naturalist author Émile Zola. Completed in 1880, Nana is the ninth installment in the 20-volume Les Rougon-Macquart series, which was to tell "The Natural and Social History of a Family under the Second Empire." The novel was an immediate success. Le Voltaire, the French newspaper that was to publish it in installments from October 1879 on, had launched a gigantic advertising campaign, raising the curiosity of the reading public to a fever pitch. When Charpentier finally published Nana in book form in February 1880, the first edition of 55,000 copies was sold out in one day.
