By his sixties, he had swallowed many books about a wide variety of people. And what the authors did not invent, diligently littering the bookstores and vastness of the Web with stories about characters who woke up in their own children's body and immediately began to change the story... But when one day our hero realized with horror that he was in the body of himself, 15-year-old, in 1978 - it turned out that the writers who remained in the 21st century shamelessly lied. For starters, you have to fight with your teenage self for supremacy. No, do not fight - negotiate, learn to get along together - step by step, finding a lot of pleasant and not very moments in this process. And then the memory threw up the most important surprise: instead of discovering unprecedented knowledge and abilities in itself, it better hides the last, most important years lived there in the future. But it is precisely in them that the key is hidden to how to take away from the country, from the planet, from their loved ones, finally, such a misfortune that trouble is in trouble for all troubles... In addition, the citizen will not have a long years to get used to, build connections, position in society. His fate is not that of a marathon runner, but that of a sprinter, at best, a middle-distance runner. And you can get to the caches of your own memory only by establishing interaction with yourself, fifteen years old. Thank you, at least there is a hint - in one book loved since childhood... Wow, a problem? And who, in fact, promised that it would be easy?
