Mal didn’t break stride, but hooked a thumb back at the river. “Because of that,” he shouted over the din of rushing water. “If we’ve been followed, it will be too easy for someone to sneak up on us with that noise as cover.”

Zoya scowled, but we pushed on, until finally we’d outdistanced the river’s clamor. We spent the night in a hollow of damp limestone where there was nothing to hear but our teeth chattering as we shivered in our wet clothes.

FOR TWO DAYS, we carried on like that, moving through the tunnels, occasionally backtracking when a route proved impassable. I’d lost all sense of what direction we were heading, but when Mal announced that we were turning west, I noticed that the passages were sloping upward, leading us toward the surface.

Mal set an unforgiving pace. To keep contact, he and the twins would whistle to each other from opposite ends of the column, making sure no one had drifted too far behind. Occasionally, he’d fall back to check on everyone.

“I can tell what you’re up to,” I said once when he returned to the head of the line.

“What’s that?”

“You pop back there when someone’s lagging, start up a conversation. You ask David about the properties of phosphor or Nadia about her freckles—”

“I have never asked Nadia about her freckles.”

“Or something. Then gradually you start to pick up the pace so that they’re walking faster.”

“It seems to work better than jabbing them with a stick,” he said.

“Less fun.”

“My jabbing arm is tired.”

Then he was gone, pressing ahead. It was the most we’d spoken since we’d left the White Cathedral.

No one else seemed to have trouble talking. Tamar had started trying to teach Nadia some Shu ballads. Unfortunately, her memory was terrible, but her brother’s was nearly perfect and he’d eagerly taken over. The normally taciturn Tolya could recite entire cycles of epic poetry in Ravkan and Shu—even if no one wanted to hear them.

Though Mal had ordered that we remain in strict formation, Genya frequently escaped to the front of the column to complain to me.

“Every poem is about a brave hero named Kregi,” she said. “Every single one. He always has a steed, and we have to hear about the steed and the three different kinds of swords he carried and the color of the scarf he wore tied to his wrist and all the poor monsters he slew and then how he was a gentle man and true. For a mercenary, Tolya is disturbingly maudlin.”

I laughed and glanced back, though I couldn’t see much. “How is David liking it?”

“David is oblivious. He’s been babbling about mineral compounds for the last hour.”

“Maybe he and Tolya will just put each other to sleep,” Zoya grumbled.

She had no business griping. Though they were all Etherealki, the only thing the Squallers and Inferni seemed to have in common was how much they loved to argue. Stigg didn’t want Harshaw near him because he couldn’t stand cats. Harshaw was constantly taking offense on Oncat’s behalf. Adrik was supposed to stay near the middle of the group, but he wanted to be close to Zoya. Zoya kept slipping away from the head of the column to try to get away from Adrik. I was starting to wish I’d cut the rope and left them all to drown in the river.
