Black City is a world on the ruins of the past—a territory where people still manage to survive. Around it lie wastelands filled with mutants and out-of-control machines, obvious dangers and hidden threats. Black City charges an enormous price for protection, but it never lets anyone down… Or it didn’t—until the day the enemy unexpectedly showed up from the inside. Mark Verger, an ordinary surgeon from the borderlands, was not the first to face this enemy, but he was the first who didn’t retreat in front of it. It seems he has no chances—no one has ever bet on him… Yet no one knew that Mark had been deceiving Black City for years. Now two powerful forces are interested in this new player, and Mark must decide which side to stay on—and who, in reality, among the eternal chaos, has become the true evil.
