Welcome to the Ark

Excerpt in the book:

Doug understood the world, all right. It was a place where guns won over knives and knives over tire irons and tire irons over fists and fists over mind. You could accept that and find a place there, or you could let it roll over you, take you out. Noah had asked him what he'd been feeling that night he'd done it. He'd had the right answer, but it wasn't pain. Rage.
