"Yeah, I was. I should tell you something. That night, when you met me, I kind of promised my friend Peris I wouldn't take any big risks. You know, in case I really got in trouble, and they got really mad."

"Who cares if they get mad? You're almost sixteen."

"But what if they get mad enough that they won't make me pretty?"

Shay stopped bouncing. "I've never heard of that happening."

"I guess I haven't either. But maybe they wouldn't tell us if it had. Anyway, Peris made me promise to take it easy."

"Tally, do you think maybe he just said that so you wouldn't come around again?"

"Huh?"

"Maybe he made you promise to take it easy so you wouldn't bother him anymore. To make you afraid to go to New Pretty Town again."

Tally tried to answer, but her throat was dry.

"Listen, if you don't want to come, that's fine," Shay said. "I mean it, Squint. But we're not going to get caught. And if we do, I'll take the blame." She laughed. "I'll tell them I kidnapped you."

Tally stepped onto her board and snapped her fingers. When she reached Shay's eye level she said, "I'm coming. I said I would."

Shay smiled and took Tally's hand for a second, squeezing. "Great. It's going to be fun.

Not new pretty fun-the real kind. Put these on."

"What are they? Night vision?"

"Nope. Goggles. You're going to love the white water."

They hit the rapids ten minutes later.

Tally had lived her whole life within sight of the river. Slow-moving and dignified, it defined the city, marking the boundary between worlds. But she'd never realized that a few kilometers upstream from the dam, the stately band of silver became a snarling monster.

The churning water really was white. It crashed over rocks and through narrow channels, catapulted up into moonlit sprays, split apart, rejoined, and dropped down into boiling cauldrons at the bottom of steep falls.
