Please help find the author of a book about the expedition,missing in the end of 18 years.. and found already in the Soviet era alive. The expedition got to the canyon,where I couldn't get out among the expedition was the couple, during this time, they have a child, at the time of their discovery he was 20-something years. The climate in the canyon was favorable, so they lived there for a long time. The guy started the hunt, as he was a wealthy heir and had not seen a woman, besides your mom. About the world that existed outside of the canyon he knew nothing, at the request of parents, the members of the expedition didn't tell him that the child does not have any hope to see it as a chance to escape over the past decade, they have not found. IN the story of the works were created by the film. But I read in his youth, so neither the author nor the title of the book and movie don't remember. Help,please can anyone remembers.
