Unusual meteorites fall to the ground. What to do? How to escape? Convenient when, on the way to home, you suddenly fall into a secret, ultra-secure bunker. There are no windows in it, and the only door is tightly closed, so how to find out what is happening outside, and most importantly... How to save the earth without leaving the bunker? A manual for strong-willed girls. The book was written by: Maksimov Ivan Andreevich, at that time a student of class 7A. This is my first book, and I will be pleased if you write a review, especially if it contains constructive criticism.
