The first adviser to the king. Davydov B.A.

The final part of the fascinating trilogy. Andrei Rusakov, a former officer of special forces, who turned out to be in the XVII century in the territory where there was a bloody war between the authorities of the Commonwealth and the rebellious hetman Khmelnitsky, achieved the implementation of his plans. For the sake of them, he entered the service of the richest tycoon Prince Vishnevetsky, introduced the production of new types of military equipment, and at times led an insidious diplomatic game. All his activities were subordinated to a great goal: to change the course of history in order to reconcile Russia and the Commonwealth, to save these states from many troubles and suffering.

Incredible efforts, accurate calculation, endurance and composure led to grandiose success. However, Andrei, with all his mind and experience, could not foresee how it would end.
