The secret of black stone

Great discoveries are simply not made. Scientists think, reason, weigh and, in the end, come to some conclusion. And there are great discoveries made by mistake. So it happened with the girl Alice Selezneva, who will live at the very end of the 21st century ...
There is no secret in the universe that Alice Selezneva could not unravel. And if Simferopol grandmother and her best friend Pashka Geraskin help her in this - then even more so!
This time, a friendly team will have to help save children from the planet Pavlonia, who flew to rest to Earth, but their ship was swallowed by a large star dragon.
