A thought occurring to him, Perrin moved down the roadway in a few jumping bursts. A hundred paces away, he looked back and confirmed his suspicions. That glass didn’t make a wall, but an enormous dome. Translucent, with a violet tint, it seemed to extend for leagues.

Hopper moved at a blur, coming to stand beside him. We must go.

“He’s in there, isn’t he?” Perrin asked. He reached out. Oak Dancer, Sparks and Boundless were near. Ahead, inside the dome. They responded with quick, frantic sendings, at hunt and being hunted.

“Why don’t they flee?” Perrin asked.

Hopper sent confusion.

“I’m going to them,” Perrin said, willing himself forward.

Nothing happened.

Perrin felt a stab of panic in his gut. What was wrong? He tried again, this time trying to send himself to the base of the dome.

It worked. He arrived in an eyeblink, that glasslike surface rising in a cliff face before him. It’s this dome, he thought. It’s blocking me. Suddenly, he understood the trapped feeling the wolves had sent. They couldn’t get away.

Was that the purpose of this dome, then? To trap wolves so that Slayer could kill them? Perrin growled, stepping up to the surface of the dome. He couldn’t pass in by imagining himself there, but perhaps he could get through by more mundane means. He raised a hand, then hesitated. He didn’t know what touching the surface would do.

The wolves sent images of a man in black and leather, with a harsh, lined face and a smile curling on his lips as he launched arrows. He smelled wrong, so wrong. He also smelled of dead wolves.

Perrin couldn’t leave them in there. No more than he could leave Master Gill and the others to the Whitecloaks. Furious at Slayer, he touched the surface of the dome.

His muscles suddenly lost strength. They felt like water, his legs unable to hold him up. He fell to the ground, hard. His foot was still touching the dome—passing through it. The dome appeared to have no substance.

His lungs no longer worked; inflating his chest was too difficult. Panicked, he imagined himself elsewhere, but it didn’t work. He was trapped, as surely as the wolves!

A gray-silver blur appeared next to him. Jaws grabbed his shoulder. As Hopper pulled him free of the violet dome, Perrin immediately felt his strength return. He gasped for breath.

Foolish cub, Hopper sent.

“You’d leave them?” Perrin said, voice ragged.

Not foolish to dig in the hole. Foolish for not waiting for me in case hornets came out. Hopper turned toward the dome. Help me if I fall. He padded forward, then touched his nose to the dome. Hopper stumbled, but righted himself and continued on slowly. On the other side, he collapsed, but his chest continued to move.

“How did you do it?” Perrin asked, rising.

I am me. Hopper as he saw himself—which was identical to who he was. Also scents of strength and stability.

The trick, it seemed, was to be in complete control of who you were. Like many things in the wolf dream, the strength of one’s mental image was more powerful than the substance of the world itself.

Come, Hopper sent. Be strong, pass through.

“I have a better idea,” Perrin said, standing up. He charged forward at full speed. He hit the violet dome and immediately went limp, but his momentum carried him to the other side, where he rolled to a stop. He groaned, shoulder hurt, arm scraped.

Foolish cub, Hopper sent. You must learn.

“Now isn’t the time,” Perrin said, climbing to his feet. “We have to help the others.”

Arrows in the wind, thick, black, deadly. The hunter’s laughter. The scent of a man who was stale. The killer was here. Hopper and Perrin ran down the road, and Perrin found that he could increase his speed within the dome. Tentatively, he tried jumping forward with a thought, and it worked. But when he tried to send himself outside, nothing happened.

So the dome was a barrier. Within it, he could move freely, but he could not move to a place outside it by imagining himself elsewhere. He had to pass the dome’s wall physically if he wanted out.

Oak Dancer, Boundless and Sparks were ahead. And Slayer, too. Perrin growled—frantic sendings flooded him. Dark woods. Slayer. He seemed so tall to the wolves, a dark monster with a face chiseled as if from rock.

Blood on the grass. Pain, anger, terror, confusion. Sparks was wounded. The other two jumped back and forth, taunting and distracting Slayer while Sparks crawled toward the border of the dome.

Care, Young Bull, Hopper sent. This man hunts well. He moves almost like a wolf, though he is something wrong.

“I’ll distract him. You get Sparks.”

You have arms. You carry. There was more to the sending than that, of course: Hopper’s age and experience, Perrin still a pup.

Perrin gritted his teeth, but didn’t argue. Hopper was more experienced than he was. They parted, Perrin reaching out for Sparks, finding where he was—hidden within a patch of trees—and taking himself directly there.

The dark brown wolf had an arrow in his thigh, and he was whimpering softly, trailing blood as he crawled. Perrin knelt quickly and pulled the arrow out. The wolf continued to whimper, smelling frightened. Perrin held the arrow up. It smelled evil. Disgusted, he tossed it aside and picked up the wolf.

Something crackled nearby, and Perrin spun. Boundless leaped between two trees, smelling anxious. The other two wolves were leading Slayer away.

Perrin turned and ran toward the dome’s nearest edge, carrying Sparks. He couldn’t leap directly to the edge of the dome because he didn’t know where it was.

He burst from the trees, heart thumping. The wolf in his arms seemed to grow stronger as they left the arrow behind. Perrin ran more quickly, using a speed that felt reckless, moving hundreds of paces with blurring speed. The dome wall approached, and he pulled to a stop.

Slayer was suddenly there, standing before him, bow drawn. He wore a black cloak that billowed around him; he was no longer smiling, and his eyes were thunderous.

He released. Perrin shifted and never saw where the arrow landed. He appeared in the place where he’d first entered the dome; he should have gone there first. He hurled himself through the violet dome, collapsing on the other side, sending Sparks tumbling.

The wolf yelped. Perrin hit hard.

Young Bull! Sparks sent an image of Slayer, dark like a thunderhead, standing right inside the barrier with bow drawn.

Perrin didn’t look. He shifted, sending himself to the slopes of Dragonmount. Once there, he leaped to his feet, anxious, hammer appearing in his hand. Groups of nearby wolves sent greeting. Perrin ign
