Less than a month has passed since the heroes of the novel “Starry Amber” - Vasily Raskosykh and Dmitry Balyasin - returned home from an archaeological expedition to the planet Titanus. They should have rested after incredible adventures on the Earth’s twin, and gained strength before the start of the new school year... But that was not the case! Dima is forced to get a job to pay off the loan. But Vasya has no time for worldly vanity. He is already obsessed with new ideas. I imagined that I could find in the protected forests of the Urals some technical device created by nature without the slightest human participation. It would seem that the mission is impossible, it is easier to find the Holy Grail... But luck favors the brave - Vasya finds a miraculous stone camera in the rocks. All that remains is to develop the photo. But not everything is so simple...
