Aria stopped listening to them. The hair on her arms lifted as her ears latched onto new sounds. Moans. Whimpers. Sickly sounds that swept toward her through the tunnel. A chorus of need.

She broke away from Molly and Reef, clutching her wounded arm to her side as she rushed ahead. Rounding a bend in the corridor, she arrived in a large, dim cavern, lit along the perimeter by lamps.

Spread across the floor on blankets lay dozens of people in varying states of consciousness. Their faces were ghastly white against their grays—the same clothes she’d worn her entire life until she’d been cast out of Reverie.

“They took ill immediately after you all arrived,” Molly said, catching up to her. “You went to Perry’s tent, and they came here, and that’s how it’s been. Perry said this same thing happened to you when you first came out of Reverie. It’s the shock to your immune systems. There were inoculations onboard the Hover you arrived in. A supply for thirty people—but there are forty-two here. We administered equal amounts to everyone, at Perry’s request. He said it’s what you’d have wanted.”

Aria couldn’t respond. Later, when she could think clearly again, she would recall Molly’s every word. She’d consider the way Reef watched her with his arms crossed, like this was her problem to fix. Now she moved further inside, her heart stuck in her throat.

Most of the people she saw were still as death. Others shook with fever, their complexions sallow, almost green. She didn’t know which was worse.

She searched the faces around for her friends—Caleb and Rune and—

“Aria . . . over here.”

She followed the voice. A pang of guilt hit her when she spotted Soren; he hadn’t come to mind. Aria stepped past the quaking bundles, kneeling at his side.

Soren had always been so burly, but now the thickness in his shoulders and neck had deflated. Even wrapped in a blanket she could tell. She could see it in his hollow cheeks and sunken eyes, which were heavy, half-lidded, but focused on her.

“Nice of you to come by,” he said, clearly more lucid than the others. “I’m a little envious you got private accommodations. Pays to know the right people, I guess.”

Aria didn’t know what to say. She couldn’t absorb this level of suffering. Her throat was choked with it. Tight with the need to help. To change this somehow.

Soren blinked tiredly. “I can see why you love the outside,” he added. “It’s mega champ out here.”

PEREGRINE

You think it’s Roar and Twig?” Gren asked, pulling his horse alongside Perry’s.

Perry inhaled, searching for traces of the riders who’d been spotted earlier. He smelled nothing but smoke.

Ten minutes ago he’d left the cave, eager for fresh air. For light and the feeling of openness and movement. What he’d gotten was a thick gray haze from the morning’s fires blanketing everything, and the stinging sensation of the Aether like soft pinpricks over his skin.

“I’d be surprised if it was someone else,” he replied. “Hardly anyone besides me and Roar knows this trail exists.”

He had hunted these woods with Roar since they were kids. They had killed their first buck together not far from here. Perry knew every bend on this path, which cut through land that had once been his father’s, then his brother’s, and then—half a year ago when he’d become Blood Lord—his.

It had changed, though. In the past months, Aether storms had started fires that sheared through the hills, leaving wide, charred stretches. The temperature was too cold for late spring, and the smells of the wood were different too. The scents of life—earth, grass, and game—seemed buried beneath the acrid stench of smoke.

Gren tugged his brown cap down. “What are the odds they have Cinder with them?” he asked. Cinder had been kidnapped while under Gren’s watch, and he hadn’t forgiven himself.

“Good,” Perry said. “Roar always comes through.”

He thought of Cinder, of how weak and frail the boy had been when he’d been taken. Perry didn’t want to think about what was happening to him in Sable and Hess’s hands. They had joined forces, Horns and Dwellers, and abducted Cinder for his ability to control the Aether. He was key to reaching the Still Blue, it seemed. Perry just wanted him back.

“Perry.” Gren reined in his horse. He angled his head, turning to better catch sounds with his keen ears. “Two horses. Riding hard right toward us.”

Perry couldn’t see anyone yet as he scanned the trail ahead, but it had to be them. He whistled to let Roar know he was there. Seconds passed as he waited for Roar’s answering call.

None came.

Perry cursed. Roar would have heard and whistled back.

He swept his bow off his shoulder and nocked an arrow, his gaze never leaving the bend in the path. Gren drew his bow as well, and they fell silent, bracing for anything.

“Now,” Gren said murmured.

Perry heard the horses, thundering closer. He drew his bowstring back, aiming at the trail, as Roar tore around a stand of birches.

Perry lowered his bow, trying to sort out what was happening.

Roar approached at a gallop, his black mount kicking up clods of dirt. His expression was focused—cold—and it didn’t change when he spotted Perry.

Twig, one of the Six like Gren, rounded the bend behind him. Like Roar, he rode alone. Perry’s hope of getting Cinder back crashed.

Roar rode hard until the last moment, and then checked his mount sharply.

For a long moment, Perry stared at him, unable to speak. He hadn’t expected to look at Roar and think Liv, though he should have. She had belonged to Roar, too. The loss landed like a blow to Perry’s stomach, as hard as it had days ago when he’d first learned.

“Good you’re back safe, Roar,” he said finally. His voice sounded strained, but he got the words out at least.

Roar’s horse stamped in agitation, tossing its head, but Roar’s gaze held steady.

Perry knew that hostile look. It had just never been directed his way.

“Where have you been?” Roar asked.

Everything about that question was wrong. The accusing tone in Roar’s voice. His implication that Perry had failed in some way.

Where had he been? Looking after four hundred people who were withering away in a cave.

Perry ignored the question, asking his own. “Did you find Hess and Sable? Was Cinder with them?”

“I found them,” Roar said coldly. “And, yes. They have Cinder. What are you going to do about it?”

Then he put his heels to his horse and rode away.

They returned to the cave without a word. The awkwardness clung to them, as dense as the smoke hanging over the woods. Even Gren and Twig—best of friends—said little to each other, their usual banter banished by the tense mood.

The hour of silence left Perry plenty of time to remember the last time he’d seen Roar: a week ago, in the eye of the worst Aether storm he’d ever been in. Roar and Aria had just come back to Tide territory after spending a month away. Seeing them together after weeks of missing Aria, Perry had lost his mind and attacked Roar. He’d swung his fists, assuming the worst of a friend who had never once doubted him.

Surely that contributed to Roar’s dark temper, but the real cause was obvious.

Liv.

Perry tensed at his sister’s memory, and his horse shied beneath him. “Whoa. Easy, girl,” he said, settling the mare. He shook his head, streaked at himself for letting his thoughts slip.

He couldn’t let himself think about Liv. Grief would make him weak—something he couldn’t afford with hundreds of lives in his hands. It would be harder to stay focused with Roar back, but he’d do it. He had no choice.

Now, as he took the switchback trail down to the protected cove below, he caught sight of Roar up ahead and told himself not to worry. Roar was his brother in every way except by blood. They’d find a way past a fight. Past what had happened with Liv.

Perry dismounted on the small beach, staying behind as the others disappeared into the dark crevasse that led into the belly of the mountain. The cave was his personal torture, and he wasn’t ready to return to it yet. When he was in there, it took every bit of his concentration to quell the panic that tightened his lungs and stole his breath away.

“You’re claustrophobic,” Marron had told him yesterday. “It’s an irrational fear of being trapped in close spaces.”

But he was also Blood Lord. He didn’t have time for fear, irrational or otherwise.

He drew a breath, savoring the outside air for a few moments longer. Afternoon ocean breezes had blown away the smoky haze, and for the first time that day, he could see the Aether.

The blue currents rolled across the sky, a tempest of luminescent, twisting waves. They were fiercer than ever—more violent than even yesterday—but something else caught his eye. He saw tinges of red where the Aether churned most intensely, like hot spots. Like the red of sunrise, bleeding through the crest of a wave.

“Do you see that?” Perry said to Hyde, who jogged out to meet him.

One of the best Seers in the Tides, Hyde followed Perry’s gaze, his hawk’s eyes narrowing. “I see it, Per. What do you think it means?”

“Not sure,” Perry said, “but I doubt it’s good.”

“I wish I could see the Still Blue, you know?” Hyde’s gaze had moved to the horizon, across endless miles of ocean. “It’d be easier to take all of this if I knew it was there, waiting for us.”

Perry hated the defeat that gathered in Hyde’s temper, a flat, stale scent like dust. “You’ll see it soon,” he said. “You’ll be the second to see it.”

Hyde took the bait. He grinned. “My eyes are stronger than yours.”

“I meant Brooke, not me.”

Hyde shoved him in the shoulder. “That’s not right. I have twice her range.”

“You’re a blind man compared to her.”

Their debate continued as they headed into the cave, Hyde’s temper lifting, just as Perry had hoped. He needed to keep morale up, or they’d never get through this.

“Find Marron for me, and get him to the Battle Room,” he told Hyde as they stepped inside. “I need Reef and Molly there as well.” He nodded to Roar, who stood a few paces away, staring across the cave with his arms crossed. “Get him water and something to eat, and have him join us right away.”

It was time for a meeting. Roar had information about Cinder, and Sable and Hess. In order to reach the Still Blue, Perry needed Dweller ships—he and Aria had taken one from Reverie, but it wouldn’t carry enough people—and he also needed a precise heading or the Tides wouldn’t go anywhere.

Cinder. Hovers. A heading.

Three things, and Sable and Hess had them all. But that was going to change.

Roar spoke with his back still turned. “Perry seems to have forgotten that I can hear his every word, Hyde.” He turned to face Perry—and there was that dark stare again. “Whether I want to or not.”

Anger washed over Perry. Nearby, Hyde and Gren tensed, their tempers spiking red, but Twig, who’d been with Roar for days, moved first.
