Anna Karenina

Anna Karenina is a novel by the Russian author Leo Tolstoy, first published in book form in 1878. Many writers consider Anna Karenina the greatest work of literature ever, and Tolstoy himself called it his first true novel. It was initially released in serial installments from 1873 to 1877 in the periodical The Russian Messenger.
A complex novel in eight parts, with more than a dozen major characters, it is spread over more than 800 pages (depending on the translation and publisher), typically contained in two volumes. It deals with themes of betrayal, faith, family, marriage, Imperial Russian society, desire, and rural vs. city life. The plot centers on an extramarital affair between Anna and dashing cavalry officer Count Alexei Kirillovich Vronsky that scandalizes the social circles of Saint Petersburg and forces the young lovers to flee to Italy in a search for happiness. After they return to Russia, their lives further unravel.
Trains are a recurring motif throughout the novel, which takes place against the backdrop of rapid transformations as a result of the liberal reforms initiated by Emperor Alexander II of Russia, with several major plot points taking place either on passenger trains or at stations in Saint Petersburg or elsewhere in Russia. The novel has been adapted into various media including theatre, opera, film, television, ballet, figure skating, and radio drama. The first of many film adaptations was released in 1911 but has not survived.
