Which novel was written by Leo Tolstoy?

Leo Tolstoy is renowned for his monumental work "War and Peace," which is regarded as one of the greatest novels in world literature. Published in 1869, "War and Peace" intricately weaves together the lives of several characters against the backdrop of historical events, particularly the Napoleonic Wars. Tolstoy delves into themes of fate, free will, and the nature of history, presenting an in-depth exploration of human experience.

The other novels mentioned are significant works but authored by different writers. "The Grapes of Wrath" is by John Steinbeck, focusing on the struggles of Dust Bowl migrants during the Great Depression. "A Farewell to Arms" is written by Ernest Hemingway, which narrates a love story set during World War I. "To Kill a Mockingbird," authored by Harper Lee, addresses racial injustice in America through the eyes of a young girl in the 1930s. Each of these works stands out in its own right, but "War and Peace" is the only novel attributed to Leo Tolstoy.
