Matt shook his leg, trying to disengage the boy. Behind him, another one snickered, taking in the spectacle as he waited his turn.

“Thorsen!” Fen snarled.

“But he’s just a—”

“He’s a Raider!” Fen yelled.

The boy lunged to bite again, and Matt grabbed him by the arm and threw him to the side. Then he looked up to see the leader smirking. The boy was twisting, scrambling to his feet, and to Matt’s left, another was getting ready to take a run at him—a kid closer to his age, but scrawny, half a foot shorter. Matt glanced back at the leader, just standing there, arms crossed.

Matt charged. He heard Fen shout “No!” but Matt didn’t stop. At tournaments, Coach Forde always tried to arrange it so Matt took on his toughest opponent first. Take care of the biggest threat while you’re fresh. If you win the round, you’re left with weaker guys who’ve just seen you knock out their best fighter.

As Matt rushed the Raider leader, he saw surprise flash across the Raider’s face. Matt barreled into the guy and sent him staggering. It was only a stagger, though, and the guy came back swinging. Matt managed to duck the first blow, but he took the second to the side of his face, his neck wrenching.

Matt swung. He landed three blows in quick succession, the last one hitting so hard the guy went flying.

As the Raider leader fell, the wind whipped up again. This time it sent Matt stumbling. His ankle twisted, and he went down on one knee. He started to rise again and—

A low growl sounded behind him.

Matt lifted his head to see a wolf standing there. A giant wolf with gray fur and inch-long fangs. The guy he’d thrown to the ground was gone.

Matt could tell himself that the wolf had somehow run in without him noticing, and the Raider leader had taken off, but one look in the beast’s eyes and he knew better. This wasthe Raider leader. The guy had turned into a wolf. Now it was hunkering down, teeth bared, ready to leap and—

Someone screamed. A long, drawn-out wail of a scream that made the wolf stop, muzzle shooting up, ears swiveling to track the sound.

Not a scream. A siren. The tornado siren.

Matt looked up and saw that the sky had turned yellow. Distant shouts and cries came from the fair as people scrambled for cover. Then, far to the left, a dark shape appeared against the yellow sky. A twister. It hadn’t touched down, but the gathering clouds seemed to drop with every passing second.

A howl snapped Matt’s attention back to the wolf. It wasn’t the beast howling; it was the wind, shrieking past, as loud and piercing as the siren. The wolf’s eyes slitted against the wind as it sliced through his fur, and he turned away from the blast.

Matt charged. He caught the wolf with a right hook to the head. The beast staggered, but only a step, better balanced on four legs than two. Then it lunged, teeth flashing. Matt caught it with an uppercut. A yelp, but the wolf barely stumbled this time, and its next lunge knocked Matt down, with the wolf on his chest. He grabbed its muzzle, struggling to keep those jaws away from his throat as the beast growled and snarled. Matt tried to kick it in the stomach, but his foot wouldn’t connect.

Someone hit the wolf’s side and sent it flying off Matt. Matt scrambled up and tackled the wolf. His rescuer did the same, both of them grabbing the beast and trying to wrestle it down. It was only then that Matt saw that it was Fen who’d come to his aid.

“Attacking a wolf?” Fen grunted as they struggled. “You’re one crazy—” The wind whipped the last word away.

Matt looked across the field. The tornado had touched down. They needed to end this and get to safety. Now.

With a sudden burst of energy, the wolf bucked. Matt lost his grip and slid off. Fen stayed draped over the beast’s back.

“Use your thing!” Fen shouted.

“What?”

“Your—” Fen’s face screwed up in frustration as he struggled to stay on the wolf’s back. “Your power thing. What you hit me with.”

How did Fen—?Not important.

Matt clenched his amulet. It had barely even warmed since the fight had begun, and now it just lay in his hand, cold metal. When he closed his eyes to concentrate, something struck his back. A chunk of wood hit the ground. A sheet of newspaper sailed past, wrapping around his arm. The next thing that flew at him wasn’t debris—it was one of the Raiders. Matt slammed his fist into the kid, then turned back just in time to see the wolf throw Fen off.

The wolf looked at Matt. Their eyes met. The wolf’s lip curled, and it growled. Even as the sirens drowned out the sound, Matt swore he could feel it vibrating through the air. Matt locked his gaze with the wolf’s. It didn’t like that, snarling and snapping now, but Matt held its gaze, and as the beast hunkered down, Matt pulled back his fist, ready to—

A black shadow leaped on the wolf’s back. Matt barely caught a flash of it before the two went down, rolling across the grass. Then all he could see was fur—gray fur and brown fur.

Two wolves. The big gray one and a smaller brown one. Matt looked over to where the wolf had thrown Fen, but he wasn’t there.

Loki. The trickster god. The shape-shifter god.

Fen was a wolf. These kids all were—which wasn’t possible. The Thorsens all said that the Brekkes didn’t know about their powers. You can’t use powers if you don’t know about them.

He looked at the wolves again.

Apparently, everyone was wrong.

Matt ran at the leader wolf. Another Raider jumped into his path. It was the little kid from earlier, but Matt was beyond worrying about fighting fair. He hit the boy with a blow to the stomach, followed by an uppercut to the jaw, and then shoved him aside.

Now the big wolf had Fen pinned, jaws slashing toward his throat. Matt jumped on the beast’s back. It reared up. Matt grabbed two handfuls of fur, but that was really all he could do. He didn’t have claws or fangs, and he wasn’t in any decent position to land a punch. Just get the thing off Fen. That was his goal. Just—

He saw something sailing toward them as fast as a rocket. A branch or—

“Duck!” he shouted to Fen as he leaped off the wolf’s back.

He hit the ground hard. He heard a yelp and rolled just in time to see the wolf staggering, a piece of pipe hitting the grass beside him. The beast snarled and tried to charge, but it stumbled and toppled, blood trickling from its ear. It hit the ground, unconscious.

Fen leaped up and they turned to face the other Raiders, who’d been standing back, letting their leader fight. Half of them were wolves now, and they were closing in, growling and snarling, eyes glittering.

A figure jumped one of the human Raiders. It was Laurie. The Raider grabbed her and threw her aside. Two of the wolves jumped Fen. The biggest ran at Matt, but he veered aside and raced toward Laurie. He caught her attacker in the side and knocked him away.

He put out a hand to help Laurie up.

She waved off the help and glowered at him. “I could have handled it.”

“I was just—”

“I’m here to help you two. Not to be rescued,” she said.

Before he could answer, the bigger Raider was on him, and Laurie’s attacker was back on his feet. Matt managed to take down his, and Laurie seemed to be doing okay with hers, but when he went to help her, a hand grabbed his shoulder.

Matt turned, fist raised. It was Fen, now back in human form. He pointed to the east, and Matt saw the twister coming. The dark shape was stirring up a debris cloud, making it seem even bigger than it was.

“We gotta run,” Fen said.

“What? No. We’re—” He slammed his fist into a charging attacker. “We’re fine. That twister—”

“Not the twister,” Fen said as he ducked a blow. He jabbed his finger east again, and Matt made out a group of figures racing across the field. Coming their way. More Raiders. He faintly caught a groan to his left and glanced over to see the big wolf rising.
