Lev Nikolayevich Tolstoy 
The Cossacks [EPUB ebook] 

Olenin was a youth who had never completed his university course, never served anywhere (having only a nominal post in some government office or other), who had squandered half his fortune and had reached the age of twenty-four without having done anything or even chosen a career. He was what in Moscow society is termed un jeune homme. But he did find a career — he took a post as a Cadet in the army, and ended up assigned to Transcaucasia. This is the place — here among the Tatars, the Chechens, and the Old Believers — this is the place where Olenin will find love in the arms of a beautiful Cossack girl — a young woman who is promised to a Cossack warrior.
