something. That night, when you met me, I kind of promised my friend Peris I wouldnât take any big risks. You know, in case I really got in trouble, and they got really mad.â
âWho cares if they get mad? Youâre almost sixteen.â
âBut what if they get mad enough that they wonât make me pretty?â
Shay stopped bouncing. âIâve never heard of that happening.â
âI guess I havenât either. But maybe they wouldnât tell us if it had. Anyway, Peris made me promise to take it easy.â
âTally, do you think maybe he just said that so you wouldnât come around again?â
âHuh?â
âMaybe he made you promise to take it easy so you wouldnât bother him anymore. To make you afraid to go to New Pretty Town again.â
Tally tried to answer, but her throat was dry.
âListen, if you donât want to come, thatâs fine,â Shay said. âI mean it, Squint. But weâre not going to get caught. And if we do, Iâll take the blame.â She laughed. âIâll tell them I kidnapped you.â
Tally stepped onto her board and snapped her fingers. When she reached Shayâs eye level she said, âIâm coming. I said I would.â
Shay smiled and took Tallyâs hand for a second, squeezing.âGreat. Itâs going to be fun. Not new pretty funâthe real kind. Put these on.â
âWhat are they? Night vision?â
âNope. Goggles. Youâre going to love the white water.â

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 sheâd 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.
Shay was skimming just above the torrent, so low that she lifted a wake every time she banked. Tally followed at what she guessed was a safe distance, hoping her tricked-up board was still reluctant to crash into the darkness-cloaked rocks and tree branches. The forest to either side was a black void full of wild and ancient trees, nothing like the generic carbon-dioxide suckers that decorated the city. The moonlit clouds above glowed through their branches like a ceiling of pearl.
Every time Shay screamed, Tally knew she was about to follow her friend through a wall of spray leaping up from the maelstrom. Some shone like white lace curtains in the moonlight, but others struck unexpectedly from the darkness. Tally also found herselfcrashing through the arcs of cold water rising from Shayâs board when it dipped or banked, but at least she knew when a turn was coming.
The first few minutes were sheer terror, her teeth clenched so hard that her jaw ached, her toes curled up inside her special new grippy shoes, her arms and even fingers spread wide for balance. But gradually Tally grew accustomed to the darkness, the roar of water below, the unexpected slap of cold spray against her face. It was wilder, and faster, and farther than sheâd ever flown before. The river wound into the dark forest, cutting its serpentine route into the unknown.
Finally, Shay waved her hands and pulled up, the back of her board dipping low into the water. Tally climbed to avoid the wake, spinning her board in a tight circle to bring it to a smooth halt.
âAre we there?â
âNot quite. But look.â Shay pointed back the way theyâd come.
Tally gasped as she took in the view. The distant city was a bright coin nestled in darkness, the fireworks of New Pretty Town the barest cold-blue shimmer. They must have climbed a long way up; Tally could see patches
