Eugene Onegin

Almost the entire work is made up of 389 fourteen-line stanzas (5,446 lines in all) of iambic tetrameter with the unusual rhyme scheme , where the uppercase letters represent feminine rhymes while the lowercase letters represent masculine rhymes. This original structure is known as the "Onegin stanza" or "Pushkin sonnet".
The story is told by a narrator (a lightly fictionalized version of Pushkin's public image), whose tone is educated, worldly, and intimate. The narrator digresses at times, usually to expand on aspects of this social and intellectual world. This narrative style allows for a development of the characters and emphasizes the drama of the plot despite its relative simplicity. The book is admired for the artfulness of its verse narrative as well as for its exploration of life, death, love, ennui, convention, and passion. Provided by Wikipedia
