Time is a capricious and unpredictable thing. But you can come to an agreement with him and make your life almost eternal. To do this, it is enough to get into a city that does not exist. But you never know how the locals will actually treat you. Denis could be called an ordinary guy, if not for one “but”. The Temporars, the inhabitants of a city that exists outside of time, chose him as a sacrifice to an ancient artifact - the Crystal of Eternity, which gives endless youth to its owners. How can a guy avoid undeserved death? And why does the main temporar look so much like himself? Editor's comment: The book is interesting not so much for its fantastic adventures in search of the source of eternal youth, but for the unexpected consequences of finding it, youth. What can eternal life mean for a person who has lost his memory - absolute happiness or death?
