It also gave him a chance to ask Dulcet about the water system in the palace without seeming suspicious. "How do you guys have hot and cold running water?" he asked.

  She told him the water was pumped from a series of hot and cold springs.

  "And then it just empties back into a spring?" he asked innocently.

  "Oh, no, that would not be fresh," said Dulcet.

  "The dirty water falls into the river beneath the palace and then flows to the Waterway."

  It was just the information he needed. The river beneath the palace was their way out. Even better, it led to the Waterway. He didn't know what that was exactly, but Vikus had mentioned it had two gateways to the Overland.

  Boots stirred again in her sleep, and Gregor patted her side to quiet her. She had not seemed to miss home until bedtime. But she looked worried when he told her it was time to go to sleep.

  "Mama?" she asked. "Liz-ee?"

  Was it only that morning that Lizzie had ridden off to camp on the bus? It seemed like a thousand years ago.

  "Home? Mama?" insisted Boots. Even though she was exhausted, he had a hard time getting her to sleep. Now he could tell by how restless she was that she was having vivid dreams.

  "Probably full of giant cockroaches and bats," he thought.

  He had no way to tell how much time had passed. An hour? Two? But what little noise he'd been able to hear through the curtain had ceased. If he was going to do this thing, he needed to get started.

  Gregor gently disengaged himself from Boots and stood up. He fumbled in the dark and found the sling Dulcet had given him. Trying to position Boots inside it proved tricky. Finally he just squeezed his eyes shut and let his other senses work. That was easier. He slid her in and slung the pack on his back.

  Boots murmured, "Mama," and her head fell against his shoulder.

  "I'm working on it, baby," he whispered back, and searched the table for the lamp. That was all he was taking. Boots, the pack, and the lamp. He'd need his hands for other things.

  Gregor groped his way to the curtain and pushed the edge aside. There was enough torchlight from the far hall for him to make out the passage was empty. The Underlanders had not bothered to post guards at his door now that they knew him better. They were making an effort to make him feel like a guest and, anyway, where would he go?

  "Down the river," he thought grimly. "Wherever that leads."

  He crept along the hall taking care to place each of his bare feet silently. Thankfully Boots slept on. His plan would disintegrate if she woke before he got out of the palace.

  Their bedroom was conveniently close to the bathroom, and Gregor followed his way to the watery sound. His plan was simple. The river ran under the palace. If he could make his way to the ground floor without losing the sound of water, he should find the place it drained into the river.

  If the plan was simple, its execution was not. It took Gregor several hours to weave his way down through the palace. The bathrooms were not always near the stairs, and he found himself having to backtrack so he wouldn't lose the sound of rushing water. Twice he had to duck into rooms and hide when he spotted Underlanders. There weren't many about, but some sort of guards patrolled the palace at night.

  Finally the sound of water became stronger, and he made his way to the lowest level of the building. He followed his ears to where the roar was loudest and sneaked through a doorway.

  For a moment, Gregor almost abandoned his plan. When Dulcet had said "river," he had pictured the rivers that flowed through New York City. But this

  Underland river looked like something out of an action adventure movie. It wasn't terribly wide, but it ran with such speed that the surface was churned into white foam. He couldn't guess its depth, but it had enough power to carry large boulders by as if they were empty soda cans. No wonder the Underlanders didn't bother to post a guard on the dock. The river was more dangerous than any army they could assemble.

  "But you must be able to travel on it -- they have boats," thought Gregor, noticing half a dozen crafts tied up above the rush of the current. They were made out of some kind of skin stretched over a frame. They reminded him of the canoes at camp.

  Camp! Why couldn't he just be at camp like a normal kid?

  Trying not to think of the bobbing boulders, he lit his oil lamp from a torch by the dock. On reflection, he took the torch as well. Where he was going, light would be as important as air. He blew out the oil lamp to save fuel.

  He carefully climbed into one of the boats and checked it out. The torch slid into a holder clearly designed for it.

  "How do you get this thing down in the water?" he wondered. Two ropes held it aloft. They were attached to a metal wheel that was affixed to the dock. "Well, here goes nothing," Gregor said, and gave the wheel a yank. It gave a loud creak, and the boat fell straight into the river, knocking Gregor on his rear end.

  The current swept up the boat like it was a dried leaf. Gregor grasped the sides and hung on as they shot into the darkness. Hearing voices, he managed to look back at the dock for a moment. Two Underlanders were screaming something after him. The river curved and they vanished from sight.

  Would they come after him? Of course they would come after him. But he had a head start. How far was it to the Waterway? What was the Waterway, arid once he got there, where did he go next?

  Gregor would have been more concerned about these questions if he wasn't trying so hard to stay alive. Along with the boulders, he had to dodge the jagged black rocks that jutted out of the water. He found an oar lying along the bottom of the boat and used it to deflect the canoe off the rocks.

  The temperature of the Underland had felt comfortably cool since he'd arrived, especially after the ninety-degree heat of his apartment. But the cold wind whipping up off the water made goose bumps rise on his flesh.

  "Gregor!" He thought he'd heard someone call his name.

  Was it his imagination or -- no! There it was again. The Underlanders must be closing in on him.

  The river swerved and suddenly he could see a little better. A long cavern lined with crystals shimmered around him, reflecting back his torchlight.

  Gregor made out a glittering beach flanking one side of the river up ahead. A tunnel led from the beach into the dark. On impulse, Gregor pushed off a rock and pointed the canoe toward the beach. He paddled desperately with the oar for the shore. Staying on the river was no use. The Underlanders were breathing down his neck. Maybe he had time to pull up on the beach and hide in the tunnel. After they'd passed by, he could wait a few hours and try the river again.

  The canoe slammed into the beach. Gregor caught himself just before his face hit the boat bottom. Boots jerked partly awake and cried a little, but he soothed her back to sleep with his voice as he struggled to pull his craft across the sand with one hand while carrying the torch with the other. "It's okay, Boots. Shhh. Go back to sleep."

  "Hi, Bat," she murmured and her head plopped back on his shoulder.

  Gregor heard his name in the distance and sped up. He had just reached the mouth of the tunnel when he ran headfirst into something warm and furry. Startled, he staggered back a few paces, dropping the torch. The something stepped out into the dim light. Gregor's knees turned to jelly and he sunk slowly to the sand.

  CHAPTER 8

  "Ah, here you are at last," said the rat idly. "By your reek we expected you ages ago. Look,

  Fangor, he has brought the pup."

  A long nose poked over the first rat's shoulder. It had a friend.

  "What a tidbit she is," said Fangor in a smooth, rich voice. "I will allow you the entire boy if I may have the sweetness of the pup to myself, Shed."

  "It is tempting, but he is more bone than meat, and she is such a morsel," said Shed. "I find myself quite torn by your offer. Stand you, boy, and let us better tell your stuffing."

  The cockroaches had been freaky, the bats intimidating, but these rats were purely terrifying. Sitting back on their haunches, they were a
good six feet tall, and their legs, arms, whatever you called them, bulged with muscle under their gray fur. But the worst part of all was their teeth, six-inch incisors that protruded out of their whiskered mouths.

  No, the worst part was that they were clearly planning to eat Gregor and Boots. Some people thought rats didn't eat people, but Gregor knew better. Even the regular-sized rats back home would attack a person if they were helpless. Rats preyed on babies, old people, the weak, the defenseless. There were stories ... the homeless man in the alley ... a little boy who'd lost two fingers ... they were too horrible to think about.

  Gregor slowly got to his feet, retrieving the torch, but keeping it down at his side. He pressed Boots back against the cavern wall.

  Fangor's nose quivered. "This one had fish for supper. Mushrooms, grain, and just a bit of leaf. Now that's flavorful, you must admit, Shed."

  "But the pup has gorged on stewed cow and cream," returned Shed. "Not to mention, she is clearly milk-fed herself."

  Now Gregor knew what all the fuss about bathing had been. If the rats could detect the handful of greens he'd eaten hours earlier, they must have an unbelievable sense of smell.

  The Underlanders hadn't been rude when they'd wanted him to bathe. They had been trying to keep him alive!

  He went from attempting to evade them to wishing desperately that they'd find him. He had to hold the rats off. It would give him time. The expression startled him. Vikus had said killing him would give the roaches no time. By "time," did the Underlanders simply mean more life?

  He brushed off his clothes and tried to adopt the rats' casual banter. "Do I have any say in this?" he asked.

  To his surprise, Fangor and Shed laughed. "He speaks!" said Shed. "What a treat! Usually we get nothing but shrieks and whimpers! Tell us, Overlander, what makes you so brave?"

  "Oh, I'm not brave," said Gregor. "Bet you can smell that."

  The rats laughed again. "True, your sweat carries much fear, but still you have managed to address us."

  "Well, I thought you might like to get to know your meal better," said Gregor.

  "I like him, Shed!" howled Fangor.

  "I like him, too!" choked Shed. "The humans are commonly most dreary. Say we may keep him, Fangor."

  "Oh, Shed, how is that to be? It would entail much explaining, and besides, all this laughter gives me hunger," said Fangor.

  "And me," said Shed. "But you must agree, to eat such amusing prey is a great pity."

  "A great pity, Shed," said Fangor. "But without remedy. Shall we?"

  And with that, both rats bared their teeth and moved in on him. Gregor slashed at them with the torch sending a trail of sparks through the air. He held it in front of him with both hands, like a sword, fully illuminating his face.

  The rats pulled up short. At first he thought they were afraid of the flame, but it was something more. They looked stunned.

  "Mark you, Shed, his shade," said Fangor in a hushed voice.

  "I mark it, Fangor," said Shed quietly. "And he is but a boy. Think you he is ...?"

  "He is not if we kill him!" Fangor growled, and lunged for Gregor's throat.

  The first bat came in so silently that neither Gregor nor the preoccupied rats saw it. It caught Fangor mid-leap, knocking him off course.

  Fangor plowed into Shed, and the rats landed in a heap. Instantly they regained their feet and turned on their assailants.

  Gregor saw Henry, Mareth, and Perdita zigzagging their bats above the rats' heads. Besides avoiding one another in limited space, they had to dodge the wicked claws of the rats. Fangor and Shed could easily leap ten feet in the air, and the sparkling ceiling of the cavern over the beach was not much higher.

  The humans began to dive at the rats, wielding swords. Fangor and Shed fought back viciously with claws and teeth. Blood began to stain the beach, but Gregor couldn't tell whose it was.

  "Flee!" Henry shouted at Gregor as he whipped past him. "Flee, Overlander!"

  Part of him wanted to, badly, but he couldn't. First of all, he had no idea where to go. His boat was high on the beach, and the tunnel ... well, he'd rather take his chances in the open than in the tunnel if he had to deal with the rats.

  More important, he knew the Underlanders were only here because of him. He couldn't just run away and leave them to face the rats.

  But what could he do?

  At that moment, Shed caught the wing of Mareth's bat in his teeth and hung on. The bat struggled to free itself, but Shed held fast. Perdita came in behind Shed, taking off his ear with one stroke of her sword. Shed gave a howl of pain, releasing Mareth's bat.

  But as Perdita pulled out of her dive, Fangor leaped onto her bat, ripping a chunk of fur off its throat and hurling her to the ground. Perdita hit her head on the cavern wall as she landed and was knocked out. Fangor loomed over her and aimed his teeth at her neck.

  Gregor didn't remember thinking of his next move, it just happened. One minute he was pressed against the wall, and the next he had jumped forward and thrust his torch into Fangor's face. The rat shrieked and stumbled backward, right into Henry's sword. Fangor's lifeless body fell to the ground, taking the sword with it.

  Fangor's shriek finally woke Boots, who took one look over Gregor's shoulder and began wailing at the top of her lungs. Her cries echoed off the walls, sending Shed into a frenzy and disorienting the bats.

  "How fly you, Mareth?" yelled Henry.

  "We can hold!" cried Mareth, although his bat was spraying blood from its wounded wing.

  Things didn't look good. Mareth's bat was losing control, Henry was unarmed, Perdita was unconscious, her bat was gasping for air on the ground, Boots was screeching, and Shed was insane with pain and fear. Though bleeding badly, he had lost none of his speed or strength.

  Mareth was trying desperately to keep the rat from Perdita, but he was just one guy. Henry flew interference, but he couldn't get in too close without a sword. Gregor crouched over Perdita holding the torch. It seemed a fragile defense against the crazed Shed, but he had to do something.

  Then Shed leaped, catching Mareth's bat by the feet. The bat slammed into the wall and so did Mareth. The rat turned on Gregor.

  "Now you die!" screamed Shed. Boots screamed back in terror as Shed lunged at them. Gregor braced himself, but Shed never made it. Instead, the rat let out a gasp and pawed at the blade that jutted through its throat.

  Gregor caught a glimpse of Luxa's bat, Aurora, flipping upright. He had no idea when she'd arrived. Luxa must have been flying completely upside down when she'd stabbed Shed. Even though Luxa had flattened herself on the bat's back, Aurora barely managed to pull out of the maneuver without scraping her off on the ceiling.

  Shed slumped back against the cavern wall, but there was no fight left in him. His eyes burned into Gregor's. "Overlander," he gurgled, "we hunt you to the last rat." And with that, he died.

  Gregor had only a moment to catch his breath before Henry landed beside him. Pushing Gregor out onto the beach, he lifted Perdita in his arms and took off, yelling, "Scorch the land!"

  Blood pouring down his face from a gash on his forehead, Mareth was already wrenching the swords from Shed and Fangor. He dragged the rats into the river, and it quickly carried their bodies away. His bat shakily regained the use of its wings and he hurdled onto its back. Mareth caught Boots's backpack and hoisted Gregor onto his stomach in front of him.

  Gregor saw Aurora hook her clawed feet into the fur at the shoulders of Perdita's injured bat. Luxa had at some point retrieved the oil lamp from the boat. As they rose into the air, she smashed it onto the ground.

  "Drop the torch!" yelled Mareth, and Gregor managed to straighten his fingers, releasing it.

  CHAPTER 9

  Gregor watched the water flash under his eyes as he clung to the bat. For a moment, he felt relieved to have escaped the rats. But the fear of hurtling through the air on a wounded bat quickly overcame him.

  Boots had her arms clasped so tightly around his neck
that he could barely breathe, let alone speak. And what would he say to Mareth, anyway? "Wow, I'm really sorry about that whole thing back on the beach?"

  He'd had no idea, of course, about the rats. But hadn't the Underlanders tried to warn him? No, they had spoken of danger, but no one had specifically mentioned rats except the cockroaches. "Rat bad," one had said. And later they had talked about how much the rats would pay to bargain with Luxa. He and Boots could have been sold to the rats, and then what?

  He felt nauseous and shut his eyes to block out the churning water. The image of the carnage on the beach filled his head, and he decided the view of the water was better. It turned to blackness as the light from the fire diminished. When light flickered off the waves again he knew they were nearing Regalia.

  A group of Underlanders waited on the dock. They whisked the unconscious Perdita and her bleeding bat away. They tried to take Mareth on a stretcher, but he brushed them off and insisted on helping to carry his bat inside.

  Gregor sat on the dock, where Mareth had shoved him as they'd landed, wishing he could disappear. Boots was quiet now, but he could feel her little muscles were rigid with fear. Fifteen, twenty minutes passed, maybe. He couldn't tell.

  "Up!" someone snarled at him, and he saw Mareth glaring down at him. The gash on his forehead was bandaged, the right side of his face bruised and swollen. "Find your feet, Overlander!" Mareth barked. Had he actually thought this guy was shy a few hours ago?

  Gregor slowly straightened his stiff legs and stood. Mareth tightly tied his hands behind his back. No question about it this time: He was definitely a prisoner. Another guard joined Mareth, and they marched Gregor ahead of them. His legs moved numbly. What would they do to him now?

  He paid no attention to where they were going. He just walked whatever way he was pushed. He had a vague sense of climbing a lot of stairs before he entered a large diamond-shaped room. There was a table in the middle of it. Mareth pushed him down on a stool by a roaring fireplace. The two guards stepped back a couple of paces, watching him like hawks.

  "I'm that dangerous," he thought foggily.

  Boots began to stir on his back. She tugged on one of his ears. "Home?" she pleaded. "Go home, Ge-go?" Gregor had no answer for her.
