Jackson raised his eyes to the two kids at the top of the mountain.

Wisps of gray fog floated overhead, making it hard to see them.

Jackson crossed his arms tightly over his chest. He narrowed his eyes and stared. He clenched his jaw as he concentrated.

Jillian must have seen the confused look on my face. She leaned toward me and whispered, “Jackson has powers. He can make things move.”

Jackson moaned to himself. He gritted his teeth, concentrating hard.

And a few seconds later, Billy and Sheena came shooting down through the wisps of fog.

They were both screaming in shock. Their black hair blew above them as they dropped.

The fog appeared to part. Kicking their legs and thrashing their arms, the two kids came rocketing down toward us.

Faster … dropping faster …

Screaming the whole way.

I had this horrifying picture in my mind — the two of them crashing to the ground, splattering at our feet.

I sucked in a deep breath and held it. My heart thudded in my chest.

Billy and Sheena hovered above us for a few seconds. They came to a complete stop in the air. Sheena’s hair fell over her face. Billy’s long scream ended with a sharp intake of breath.

Jackson cried out, and his hands shot above his head. Then he waved the two kids down … waved them slowly down, as if they were on wires.

They landed gently on their feet.

Billy swallowed hard. His eyes were bulging. He was panting like a dog. He held on to his sister as if trying to stay on his feet.

Sheena took a shaky step toward us. She brushed back her hair and smiled. “Wow,” she said. “That’s the best ride yet!”

We all laughed. Some kids cheered. Matt slapped Jackson on the back. “Way to go, dude!”

We gathered happily around Billy and Sheena. We all shouted our questions at once.

“What happened? How did you get up there?”

“Where are the others? Are they okay?”

“Why were you on the mountain?”

Sheena raised a hand to silence us. She turned to Jackson. “How did you DO that?” she demanded. “How did you bring us down?”

Jackson grinned at her. “It’s easy if you know how,” he said.

Sheena turned to the rest of us. “I don’t know where the other kids are,” she said. “We lost them. We got separated.”

“Sheena and I climbed the mountain to look for them,” Billy said. “It was easy to climb up. But then …”

“We couldn’t get down,” Sheena said. She shuddered. “Billy and I have had a lot of creepy adventures in the past. But this park is horrible!”

“Those shadow people are everywhere,” Billy said. “We didn’t see anyone who is ALIVE!”

“And it’s always gray and dark,” Sheena added. “It’s … it’s scarier than HorrorLand.” A sob escaped her throat. Her shoulders began to tremble.

Carly Beth wrapped her arms around Sheena. “You’re okay now,” she said softly. “We’re all here with you.”

“We’re much safer here than in HorrorLand,” Jillian said. “Byron told us that. We know we can trust Byron.”

“We just have to find the other kids,” Jackson said. “Then we can find a way to get home.”

Carly Beth gave Sheena a tissue, and she wiped the tears from her eyes.

“I think we’re in trouble,” Billy said. “Sheena is the brave one in our family!”

Matt stepped up to Billy. “Have you seen Britney and Molly?”

“No,” Billy answered.

“You escaped to Panic Park with your sister and four other kids,” Matt said. “Michael, Sabrina, Boone, and Abby. How did you get separated from them?”

“I … I don’t know,” Billy replied.

“My dumb brother insisted we all go on this ride,” Sheena said. “He got tired of waiting for the rest of you to come here.”

“Don’t call me dumb, stupid!” Billy snapped. “We didn’t even know if the rest of you guys were coming or not,” Billy said. “So we all went on a ride. It’s called The Tunnel of Hate.”

“The ride was open?” I asked. “Was someone running it?”

“I don’t know,” Billy answered. “It’s a boat ride. Sheena and I got in the first boat. They came after us. It seemed like fun at first. But then … it got weird.”

“Billy and I wanted to get out,” Sheena said. “But when we turned around to look for the others … they were GONE!”

“They disappeared,” Billy said. “They weren’t in the tunnel. We searched for their boat. We couldn’t find them.”

“So we got out and looked for them,” Sheena explained. “We wandered around the park. It’s so totally creepy. And those frightening shadow people kept following us … watching us.”

“We didn’t know where to look,” Billy said. “So we climbed the mountain. We thought we’d have a better view up there. But we didn’t see them.”

“Whoa. Wait a sec,” Matt said. He locked his eyes on Billy. “You didn’t see the other four kids anywhere else in the park. So do you think they might still be in The Tunnel of Hate?”

Billy and Sheena both shrugged.

“It’s very dark in there,” Sheena said. “Very hard to see anything.”

“They could still be in there,” Billy said.

Matt waved us forward. “Let’s go for a boat ride,” he said.
