ABSTRACT When revenge turns into the meaning of life, any methods are used, and yesterday's taboos become just the next steps on the path to the goal. When a person’s most precious thing is taken away from him, and his most sacred thing is trampled into the dirt, he will immediately step over any principles in order to answer the enemy in kind. It doesn’t matter how many lives will be taken, how many destinies will be broken and how many curses will be thrown at him. Now he is driven by one thing - an unbridled thirst for revenge... In the fourth book of the "Black Crows" series, we will talk about a carefully thought-out plan for revenge, which Andrei Voronov will implement step by step. “An eye for an eye” - this is the principle that one of the main characters will be guided by, choosing as a target the most valuable thing that his enemy has. He will plunge the entire Ahmed family into a hellish whirlpool of loss and pain, so that those who dare to touch what is most dear to them will pay for it in full. But no one knows exactly who will fall into the deadly noose and on whose neck it will be tightened in a treacherous knot... From the poster: for for the display, we thank the crazy author, who deletes constructive criticism, imagines herself to be the smartest and calls customers stinking trolls.
