“ Then, Zil and a half dozen of his crew swaggered into the plaza from the far side. Astrid clenched her jaw. Would the crowd turn on them? She almost hoped so. People thought because she wouldn’t let Sam go after Zil she must not really despise the Human Crew’s Leader. That was wrong. She hated Zil. Hated everything he had done and everything he had tried to do.Edilio moved quickly between Zil and a few of the boys who had started toward him, sticks and knives at the ready.Zil’s kids were armed with knives and bats, and so were those who wanted to take them on. Edilio was armed with an assault rifle.Astrid hated that this was what life so often came down to: my weapon is bigger than your weapon.If Sam were here it would be about his hands. Everyone had either seen what Sam could do, or heard the stories retold in vivid detail. No one challenged Sam. ”
