Every time Aunt Fé comes to visit, the perfectly ordinary life of the Federmann family is thrown into disarray. The ancient, lively lady has a lot up her sleeve. After a long life filled with experiences of inflation, inheritances, and bankruptcies, along with poverty, waste, and exile, she is now wealthy and lives alone in her villa by Lake Geneva. But what does Aunt Fé want from the Federmanns, her only relatives? She definitely doesn't want to be bored. That's why she invites the three Federmann children to a luxury hotel, pampering, astonishing, and exciting them. Finally, they feel taken seriously and receive answers to questions like: Where does the money come from? Why are even billions and trillions never enough? What does a central bank think when it prints debt? Why is there no economy without a shadow market, black market, black money, and undeclared work? And why does it hail?.
