The post-office girl - Stefan Zweig

It's the 1930s. Christine, A young Austrian woman whose family has been impoverished by the war, toils away in a provincial post office. Out of the blue, a telegram arrives from an American aunt she's never known, inviting her to spend two weeks in a Grand Hotel in a fashionable Swiss resort. She accepts and is swept up into a world of almost inconceivable wealth and unleashed desire, where she allows herself to be utterly transformed. Then, just as abruptly, her aunt cuts her loose and she has to return to the post office, where - yes - nothing will ever be the same.
