Sonya, 15 at the start of the novel, is Count Rostov’s cousin. The Rostovs have taken her in because she’s orphaned and without means. She has strong romantic feelings for her second cousin Nikolai. However, because of her loyal sense of indebtedness to the Rostovs, she refrains from pushing Nikolai to marry her since it would be a financially poor match for him. In 1806, she rejects a marriage proposal from Dolokhov. Sonya is a humble young woman who’s usually in the shadow of her best friend, Natasha. When Nikolai lives at Otradnoe during the winter of 1810, Sonya and Nikolai rekindle their romance. In response to Countess Rostov’s mounting hostility, however, she eventually writes to Nikolai to release him from his promise to marry her, sacrificing herself for the family’s wellbeing.
