Function: You. Domna Yu.

The world in which the Second World War had a different - shocking - outcome.

The world in which humanity suddenly discovered, which has long shared the earth with two more developed races.

The world in which you are the function of the system. You can unite with someone else to make a double function. You can give your life in favor of another - your counterfunction. But forever you will remain only a modest line in the array of data that will scrupulously collect and analyze a certain capable calculating and weighing the probabilities of the onset of all possible options for the future.

Not the best world in order to try to be a good person.

Not the best world to love. To be passionately and disinterested to help. In order to regret a sick girl, to agree to take her place in the matrix of life and death, and go to Daedalus Labyrinth.

But there is no better.
