Novel by the German author Thomas Mann, published in 1924. German title: Der Zauberberg. Set in a Davos/ Switzerland mountain sanatorium in the years before World War I, it follows Hans Castorp, a patient from northern Germany as time passes in the sanatorium - slowly, at first, but then, the days fly by.
Der Zauberberg is enjoyable on many different levels. It explores ideologies, namely classical liberalism and communism, bourgeois thinking, religion and metaphysics. Its language is gorgeous, filled with tongue-in-cheek irony and subtle humor.
Despite its close to 1,000 pages, it is an immensely enjoyable book, that is worth re-reading over and over again. It has attained a certain cult following, and many people visit Davos to see the real sanatorium there.
