Sweden, summer trip, 2011. Petra, the amateur astrophysicist, calculates that the Earth's atmosphere will collapse that same year, on September 21, at exactly 21:20. The doomsday prophet is now traveling together in a caravan with Johann, who is somewhat inexperienced in life's affairs, but who cooks masterfully, and Agnes, the old girl with purple hair, who has learned to a high degree how to earn money on the Internet. They must hurry. Even before the destruction of earthly life, they must find and hold accountable those who made their lives miserable. Their journey leads from Sweden through Denmark and Switzerland to Italy, where Johan's brother works as a subordinate diplomat. In the meantime, they run into the major figures of world politics and thoroughly subvert international diplomatic life. The journey doesn't end in Rome, and of course nothing goes as planned... In his new book, Jonas Jonasson is in his element again: he takes his lovable heroes on amazing adventures and makes sure that his readers face the history of our time with tears in their eyes.
