About the book: 2020 / Twins Lera and Maxim are happy - rest and work at the resort in New Ingersham are ahead. But on the eve of their arrival, an earthquake occurs in the city, and then the sea washes up to the pier, an ancient ship blackened by time, in the hold of which a mysterious cargo is discovered. A chain of strange events unfolds, and Lera and Maxim accidentally - and perhaps not by coincidence - find themselves drawn into them, along with their new friends - the funny Svetka and Dan, whose appearance on the seashore was no less mysterious than the appearance of an ancient frigate. They don’t even know what amazing discoveries await them... But how could it be otherwise if former members of the sinister corporation “Extropolis” are lurking in the city?»?
