A gentleman in Moscow by Amor Towles

In 1922 Count Rostov is deemed an unrepentant aristocrat by a Bolshevik tribunal. He is sentenced to house arrest in The Metropol, a grand hotel across the street from the Kremlin. Rostov, an indomitable man of erudition and wit, has never worked a day in his life, and must now live in an attic room while some of the most tumultuous decades in Russian history are unfolding outside the hotel's doors. Unexpectedly, his reduced circumstances provide him a doorway into a much larger world of emotional discovery.
