Hurry and save the princess!

Amazing events sometimes happen to ordinary children from our world and time. But no less amazing adventures happen to children from parallel realities. For example, a ten-year-old princess managed to slam the door between worlds the day before her birthday.... Exclusively because of a mischievous cat. And now she cannot get home. To find a way out, she will have to seek friends in the place where she found herself. Asking for help from a "nerd" named Karpov. Although he is a bore and an excellent student. As it turns out during the search for a way out, nerds can find unconventional solutions, possess useful knowledge, and know how to be friends. And in general, by the end of the journey, the heroes will learn a lot about themselves. For younger school age.
