The Magic Mountain by Thomas Mann (1924). Hans Castorp visits his cousin at a sanatorium in the mountains of Switzerland. Soon he too becomes ill (maybe) and checks into the hospital—for seven years. In this sanctuary, Hans and the sanatorium’s denizens endlessly debate questions of morality, politics, and culture, as the “real world” moves inexorably toward the horror of World War I. A meditation on time, an inquiry into how life ought to be lived, and an unflinching look at evil, Mann considered the ideas in his monumental novel so challenging that he said it must be read at least twice.
