Game in reality. Kalugin A.

No one knows exactly how many options for reality exists. Some differ from each other only by insignificant details. Others seem to be embodied fantasies about the best of the worlds. Still others are similar to delusional visions. As long as you remain in your reality and consider it the only possible, nothing threatens you. But, if the game begins in reality, then life itself is put on the map. Two friends find themselves in the center of a strange and incomprehensible game, which is among themselves by two groups from the future. To escape from the pursuers, they take possession of the device that allows you to change possible options for reality, after which a crazy race begins. Changing one reality after another, the heroes of the novel get the opportunity with their own eyes to see the most diverse options for the development of historical events at the fracture of the centuries. Sometimes those that they could not even imagine, and sometimes - which were scary to even think about. But first of all, the heroes should deal with their own destinies - this is the only way to win in the game in reality.
