About the book: year / December 5, 2010. Sunday. 10:05. Leningrad region. Forest in the vicinity of the village of Nazia. Five people walked slowly along a winter forest clearing. Four of them were teenagers, aged sixteen or seventeen. Their names were Sergey, Valera, Lisa and Katya. They were students at a boarding school for orphans. The fifth in this campaign was a middle-aged man who taught physics, chemistry, geography and, most interestingly, labor at the same boarding school. In ordinary schools this subject has not been available as such for several years. If some thing could be done with your own hands, then Sergei Petrovich would do it and teach it to others.
