Arthur, the Hero of Alternative Realities, wandered from world to world, and everywhere he had to defend his right to live with a weapon. He dreamed of returning home—to our world—and at last he managed. But he couldn’t. Now he is in the world of fugitives and exiles—those hiding from the police of Antivkar. Here he realized with horror that both our world and this world of fugitives are under someone else’s sights. You can’t wait for their strike, because there’s no chance to stand your ground. You have to attack—but how?
