"Did they take you out?" I asked.

He shrugged. "Didn't need to go anymore."

I peered down the road again. The bus was late. It was often late. Sometimes it didn't come at all, and I had to walk back to my building, where my father would unplug the old car and drive me to the school in town. Will was already there, a full hour earlier, because he had to empty the basins before the sun evaporated the small amount of water that collected as dew. Last year two other girls rode the bus with me, but one day they stopped coming and never returned. It was boring waiting alone. I welcomed the distraction.

"I've got a brother," I said. "He passed his army physical."

"Easy."

"He had to do fifty pushups."

"I can do a hundred."

The boy kneeled like he was going to start exercising right there in the dust. The place where he had spilled his cup was completely dry; I couldn't even tell it had been wet. I could see the elastic band of his underwear and the smooth skin where his back was exposed. No marks, scratches, or scabs of any kind. My own hands looked like some kind of treasure map, except the lines didn't lead to riches.

"I'm Vera," I said to his back.

"Kai," he said, standing up.

"Where did you get the water?"

"I've got lots of water."

"Are you rich?"

"I guess so."

"Should you be out alone?"

"Ha!" he snorted. "I'd like to see them try something."

It wasn't clear whom he was talking about, but I didn't think Kai-or any boy-could stand up well to the bandits and soldiers who menaced our town, no matter how many pushups he could do.
