Trying to ignore the doubt that was seeping into his mind about the plan, Thomas continued on. Now it was his turn.

He snatched a vine with both hands and started to climb, directly over the spot where he'd just tied up Alby. The thick leaves of the ivy served well as handholds, and Thomas was elated to find that the many cracks in the stone wall were perfect supports for his feet as he climbed. He began to think how easy it would be without . . .

He refused to finish the thought. He couldn't leave Alby behind.

Once he reached a point a couple of feet above his friend, Thomas wrapped one of the vines around his own chest, around and around several times, snug against his armpits for support. Slowly, he let himself sag, letting go with his hands but keeping his feet planted firmly in a large crack. Relief filled him when the vine held.

Now came the really hard part.

The four vines tied to Alby below hung tautly around him. Thomas took hold of the one attached to Alby's left leg, and pulled. He was only able to get it up a few inches before letting go—the weight was too much. He couldn't do it.

He climbed back down to the Maze floor, decided to try pushing from below instead of pulling from above. To test it, he tried raising Alby only a couple of feet, limb by limb. First, he pushed the left leg up, then tied a new vine around it. Then the right leg. When both were secure, Thomas did the same to Alby's arms—right, then left.

He stepped back, panting, to take a look.

Alby hung there, seemingly lifeless, now three feet higher than he'd been five minutes earlier.

Clangs from the Maze. Whirrs. Buzzes. Moans. Thomas thought he saw a couple of red flashes to his left. The Grievers were getting closer, and it was now obvious that there were more than one.

He got back to work.

Using the same method of pushing each of Alby's arms and legs up two or three feet at a time, Thomas slowly made his way up the stone wall. He climbed until he was right below the body, wrapped a vine around his own chest for support, then pushed Alby up as far as he could, limb by limb, and tied them off with ivy. Then he repeated the whole process.

Climb, wrap, push up, tie off.

Climb, wrap, push up, tie off. The Grievers at least seemed to be moving slowly through the Maze, giving him time.

Over and over, little by little, up they went. The effort was exhausting; Thomas heaved in every breath, felt sweat cover every inch of his skin. His hands began to slip and slide on the vines. His feet ached from pressing into the stone cracks. The sounds grew louder—the awful, awful sounds. Still Thomas worked.

When they'd reached a spot about thirty feet off the ground, Thomas stopped, swaying on the vine he'd tied around his chest. Using his drained, rubbery arms, he turned himself around to face the Maze.

An exhaustion he'd not known possible filled every tiny particle of his body. He ached with weariness; his muscles screamed. He couldn't push Alby up another inch. He was done.

This was where they'd hide. Or make their stand.

He'd known they couldn't reach the top—he only hoped the Grievers couldn't or wouldn't look above them. Or, at the very least, Thomas hoped he could fight them off from high up, one by one, instead of being overwhelmed on the ground.

He had no idea what to expect; he didn't know if he'd see tomorrow. But here, hanging in the ivy, Thomas and Alby would meet their fate.

A few minutes passed before Thomas saw the first glimmer of light shine off the Maze walls up ahead. The terrible sounds he'd heard escalate for the last hour took on a high-pitched, mechanical squeal, like a robotic death yell.

A red light to his left, on the wall, caught his attention. He turned and almost screamed out loud—a beetle blade was only a few inches from him, its spindly legs poking through the ivy and somehow sticking to the stone. The red light of its eye was like a little sun, too bright to look at directly. Thomas squinted and tried to focus on the beetle's body.

The torso was a silver cylinder, maybe three inches in diameter and ten inches long. Twelve jointed legs ran along the length of its bottom, spread out, making the thing look like a sleeping lizard. The head was impossible to see because of the red beam of light shining right at him, though it seemed small, vision its only purpose, perhaps.

But then Thomas saw the most chilling part. He thought he'd seen it before, back in the Glade when the beetle blade had scooted past him and into the woods. Now it was confirmed: the red light from its eye cast a creepy glow on six capital letters smeared across the torso, as if they had been written with blood:

WICKED

Thomas couldn't imagine why that one word would be stamped on the beetle blade, unless for the purpose of announcing to the Gladers that it was evil. Wicked.

He knew it had to be a spy for whoever had sent them here—Alby had told him as much, saying the beetles were how the Creators watched them. Thomas stilled himself, held his breath, hoping that maybe the beetle only detected movement. Long seconds passed, his lungs screaming for air.

With a click and then a clack, the beetle turned and scuttled off, disappearing into the ivy. Thomas sucked in a huge gulp of air, then another, feeling the pinch of the vines tied around his chest.

Another mechanical squeal screeched through the Maze, close now, followed by the surge of revved machinery. Thomas tried to imitate Alby's lifeless body, hanging limp in the vines.

And then something rounded the corner up ahead, and came toward them.

Something he'd seen before, but through the safety of thick glass. Something unspeakable. A Griever.

CHAPTER 19

Thomas stared in horror at the monstrous thing making its way do the long corridor of the Maze.

It looked like an experiment gone terribly wrong—something from a nightmare. Part animal, part machine, the Griever rolled and clicked along the stone pathway. Its body resembled a gigantic slug, sparsely covered in hair and glistening with slime, grotesquely pulsating in and out as it breathed. It had no distinguishable head or tail, but front to end it was at least six feet long, four feet thick.

Every ten to fifteen seconds, sharp metal spikes popped through its bulbous flesh and the whole creature abruptly curled into a ball and spun forward. Then it would settle, seeming to gather its bearings, the spikes receding back through the moist skin with a sick slurping sound. It did this over and over, traveling just a few feet at a time.

But hair and spikes were not the only things protruding from the Grievers body. Several randomly placed mechanical arms stuck out here and there, each one with a different purpose. A few had bright lights attached to them. Others had long, menacing needles. One had a three-fingered claw that clasped and unclasped for no apparent reason. When the creature rolled, these arms folded and maneuvered to avoid being crushed. Thomas wondered what—or who—could create such frightening, disgusting creatures.

The source of the sounds he'd been hearing made sense now When the Griever rolled, it made the metallic whirring sound, like the spinning blade of a saw. The spikes and the arms explained the creepy clicking sounds, metal against stone. But nothing sent chills up and down Thomas's spine like the haunted, deathly moans that somehow escaped the creature when it sat still, like the sound of dying men on a battlefield.

Seeing it all now—the beast matched with the sounds—Thomas couldn't think of any nightmare that could equal this hideous thing coming toward him. He fought the fear, forced his body to remain perfectly still, hanging there in the vines. He was sure their only hope was to avoid being noticed.
