The Magic Mountain:

In this dizzyingly rich novel of ideas, Mann uses a sanatorium in the Swiss Alps, a community devoted exclusively to sickness, as a microcosm for Europe, which in the years before 1914 was already exhibiting the first symptoms of its own terminal irrationality. The Magic Mountain is a monumental work of erudition and irony, sexual tension and intellectual ferment, a book that pulses with life in the midst of death.
