The Equilibrium Principle

The Principle of Equilibrium is the fantastic novel by Alex Kosh, the third book of the “Adrenaline” cycle, genre action fantasy, urban fantasy. The “Red Dragon” club has only recently become part of the Rating of the world’s best fighters—and now its members are left without a teacher. Sensei is in a coma, and ahead of them is a fight to the death with a very strong opponent. Their training is taken on by a mysterious brother-and-sister pair—“combat maid” Elena and a strict guard named Ivan—and their training methods might turn out to be more dangerous than the fights of the Rating themselves. And most importantly, four friends have to decide who exactly among them will step into the deadly duel and risk their life.
