The Death of Ivan Ilych. A Comfortable Life, a Sudden Illness, and the Truths a Dying Man Finally Faces

Ivan Ilych has spent his life doing everything correctly - the right career, the right marriage, the right social standing - until a minor injury turns into a fatal illness, and he is forced to confront, alone, what any of it actually meant. Tolstoy's short, devastating novella strips away every comfortable illusion about a well-lived life. Brief enough to read in an afternoon, heavy enough to sit with for years.
One of the most quietly unsettling works in Russian literature, and a natural pairing with Anna Karenina for readers ready to go deeper into Tolstoy.
