Perhaps only children can correct the mistakes of adults! At least that’s what happened in this book. This story about a boy and a girl - Karina and Egor, who set themselves a noble goal - to save a small piece of pristine nature in order to prevent a global environmental disaster in a parallel dimension of planet Earth - will not leave both young and adult readers indifferent. The book teaches friendship and mutual assistance and simply takes us back to our good, cloudless childhood.
