Lost World. What is it? What kind of world do we think is lost? The one that is lost in the abyss of the elements or the one where people have forgotten how to think? The world that is hidden by time or the one where there are no more feelings, and life goes according to the given algorithms? Or maybe the lost world is a world in which there is no love left and there is no hope of returning it? Or is the lost world the world around you, or is it yourself? Where can I find answers to these questions? The heroes of this book are also looking for lost worlds, but will they be able to find a new world and not lose their own?
