By the time he was sixty, he had swallowed down countless books about the most diverse reincarnators—but one day, with horror, he realized he was in the body of a fifteen-year-old in 1978, and it turned out that writers shamelessly lied. First, you have to negotiate with your own teenage self and learn to live together. And then an unpleasant surprise came with his memory: it turns out it hides from the rightful owner the last, most important years spent there—in the future. And it is precisely those years that hold the key to how to avert from the country and his loved ones such a disaster—disaster of all disasters… Besides, a reincarnator doesn’t have years to adjust and build connections. His fate is not that of a marathon runner, but a sprinter. And you can reach the hiding places of your own memory only by establishing interaction with your fifteen-year-old self. Thanks, at least there’s a hint—inside one favorite childhood book. What a task, right? And who, exactly, promised it would be easy?
