The meat all rotted. People were stupid and careless, and there’s nothing we can do about that now.” Sam swallowed the bitterness he felt, the anger he felt at his own foolishness. “But we have food sitting out in the fields.

He accepted a congratulatory slap on the back from a creepy kid named Antoine, part of Zil’s little posse.“Because it would mean getting some kids killed,” Sam said bluntly. “We’d be lucky to rescue any of the food, and we’d end up digging more graves in the plaza.
