Gregor turned abruptly to go back. Ripred, as if anticipating just this move, spun Gregor forward and snagged the backpack with his teeth. Gregor felt himself lifted into the air as Ripred ran flat out for the far side of the river.

  "Boots!" yelled Gregor. "Boots!"

  Ripred moved like lightning. As he reached the opposite bank, he dumped Gregor on the ground and joined Luxa and Henry, who were frantically trying to hack through the silk ropes supporting the bridge.

  Gregor aimed his flashlight and saw that Gox was about three quarters of the way across. Behind her, carrying his sister, Temp struggled along with Boots. Between Boots and the twenty killer rats that were now streaming across the bridge -- there was only Tick.

  "Boots!" Gregor screamed, and dove back for the bridge. Ripred's tail caught him across the chest and flung him back onto the ground, knocking the wind from him. He gasped, trying to fill his lungs, then got to his knees and crawled toward the bridge. He had to help her. He had to.

  Gox zipped off the bridge and began to snap threads with her jaws. "No!" coughed Gregor. "My sister!" He pulled up to his feet just in time to catch another blow from Ripred's tail.

  The roaches were within ten feet of the bank when the rats caught up with them. There was no discussion between them; it was as if the bugs had worked out this whole scenario long ago. Temp put on a burst of speed for the end of the bridge, and Tick turned to face down the army of rats alone.

  As they bounded at her, Tick flew directly into the face of the lead rat, causing it to startle back in surprise. Until that moment, Gregor hadn't even realized the roaches had wings. Maybe the rats didn't know, either. But it didn't take them long to recover. The lead rat sprang forward and crushed Tick's head in its jaws.

  Temp collapsed on the bank just as the bridge gave way. Twenty rats, the leader still holding Tick in its teeth, plunged into the river below. As if this sight wasn't horrific enough, the water churned as enormous piranha-like fish surfaced and fed on the screaming rats.

  CHAPTER 23

  "Move it, move it, move it!" instructed Ripred, herding them all from the open bank and into a tunnel. He forced them along for a few minutes until they were well out of sight and, hopefully, out of smell of the tunnel entrance. At a small chamber, he gave the order to halt. "Stop you. Sit you. Slow your hearts."

  Wordlessly, the remaining members of the quest sunk to the floor of the tunnel. Gregor sat with Temp, his back to the others. He pawed up Temp's back, found Boots's hot little fingers, and entwined them with his own. He had almost lost her. Lost her for good. She would never have had the chance to meet their dad or get back to his mom's arms or play in the sprinkler with him and Lizzie or do anything ever again.

  He did not want to look at the rest of the questers. Every one of them would have watched Boots and the crawlers fall into the river to stop the rats. He had nothing to say to them.

  And then there was Tick. Brave little Tick, who had flown into the face of an army of rats to save his baby sister. Tick -- who never spoke much. Tick -- who shared her food. Tick -- who was after all just a roach. Just a roach who had given all the time she had left so that Boots could have more.

  Gregor pressed Boots's fingers against his lips and felt scalding tears begin to slide down his cheeks. He hadn't cried, not the whole time he'd been down here, and there had been plenty of bad stuff. But somehow Tick's sacrifice had crushed whatever thin shell remained between him and sorrow. From now on, he felt an allegiance to the roaches that he knew would never fade. He would never again take a roach's life. Not here and not -- if by some miracle they made it home -- in the Overland.

  He felt his shoulders began to shake. Probably the others thought he was ridiculous, crying over a roach, but he didn't care. He hated them. He hated them all.

  Temp, whose antennas had drooped down over his head, reached out and touched Gregor with a feeler. "Thank you. To weep when Tick has lost time."

  "Boots would weep, too, if she weren't..." Gregor couldn't go on as another wave of sobs swept over him. He was glad Boots hadn't witnessed Tick's death. She would have been upset and she wouldn't have understood it. He didn't really understand it, either.

  Gregor felt a hand on his shoulder and jerked away. He knew it was Luxa, but he didn't want to talk to her. "Gregor," she whispered sadly. "Gregor, know you we would have caught Boots and Temp if they fell. We would have caught Tick, too, had there been any reason."

  He pressed his hand against his eyes to stop his tears, and nodded. Well, at least that was a little better. Of course Luxa would have dived after Boots if she'd fallen. The Underlanders didn't worry about falling the way he did, not with their bats.

  "It's okay," he said. "I know." When Luxa sat beside him, he didn't move away. "I guess you think it's pretty stupid, me crying over a roach."

  "You do not yet know the Underlanders if you think we lack tears," said Luxa. "We weep. We weep, and not just for ourselves."

  "Not for Tick, though," said Gregor with a trace of bitterness.

  "I have not wept since the death of my parents," said Luxa quietly. "But I am thought to be unnatural in this respect."

  Gregor felt more tears slipping down his cheeks when he thought of how badly you had to be hurt to lose the ability to cry. He forgave Luxa everything at that moment. He even forgot why he needed to forgive her.

  "Gregor," she said softly when his tears had stopped. "If you return to Regalia, and I do not... tell Vikus that I understood."

  "Understood what?" asked Gregor.

  "Why he left us with Ripred," said Luxa. "We had to have a gnawer. I see now he was trying to protect us."

  "Okay, I'll tell him," said Gregor, wiping his nose. He was quiet for a minute, and then he asked, "So, how often do we give Boots that medicine? She still feels pretty hot."

  "Let us dose her now, before we move on," said

  Luxa, stroking Boots's forehead. Boots murmured in her sleep but didn't wake up. They slipped a few more drops from the bottle between her lips.

  Gregor stood up and tried to shake off the pain. "Let's get going," he said, not looking at Ripred. The rat had been in tons of wars. He'd probably seen lots of creatures killed. He'd told Gox to eat Treflex. Gregor was sure Tick's death affected him as little as ... well, as swatting a roach affected people in New York.

  But when Ripred spoke, his voice lacked its usual snide tone. "Take heart, Overlander. Your father is nearby."

  Gregor lifted his head at the words. "How nearby?"

  "An hour's walk, no more," said Ripred. "But so are his guards. We must all proceed with extreme caution. Bind your feet in webs, speak not, and stay close behind me. We had rare luck at the bridge. I do not think it follows us where now we go."

  Gox, whom Gregor was beginning to appreciate more as time passed, quickly spun thick silk slippers to pad their feet. As Gregor held his flashlight for Luxa to put on her pair, the light faded. He dug in his pack and came up with the last two batteries.

  "How much longer can your torchlight last?" Gregor asked Luxa. He had noticed they'd gone to one torch when they met up with Ripred, apparently to conserve fuel. Now the one torch burned low.

  "A short time only," admitted Luxa. "Your light stick?"

  "I don't know," said Gregor. "These are my last batteries, and I don't know how much power's left in them."

  "Once we have your father, we will not need light. Ares and Aurora can get us home in the dark," said Luxa encouragingly.

  "They're going to have to," said Gregor.

  The questers regrouped. Ripred led with Temp and Boots behind him. The tunnel was large enough for Gregor and Gox to walk beside them. Aurora and Ares fluttered along next, making short, silent flights. Henry and Luxa brought up the rear on foot, swords drawn. Ripred gave them a nod and they started off, deep, deep into enemy territory.

  They tiptoed along, scarcely daring to breathe. Gregor froze every time a pebble moved beneath his foot, thinking he had triggered another rat assault. He was very afraid, bu
t a new emotion was rising up in him, giving him strength to keep putting one foot in front of the other. It was hope. It flowed through him, insisting that he break his rule. His father was nearby. He would see him soon. If only they could keep moving forward undetected, he would see him soon.

  When they had been creeping along for about half an hour, Ripred suddenly stopped at a bend in the tunnel. The whole party pulled up behind him. Ripred's nose twitched furiously and he crouched.

  A pair of rats sprang from around the bend. In an impossible move, Ripred tore out one's throat with his teeth while his back feet blinded the second. In another flash, both rats lay dead. No one else had had time to raise a hand. Ripred's defense confirmed what Gregor had suspected the first moment he'd looked in his eyes. Even among rats, Ripred was lethal.

  Ripred wiped his muzzle on one of the dead rats and spoke in a whisper. "Those were the guards to this passage. We are about to enter open space. Stay against the wall, single file, for the earth is unstable and the fall immeasurable." Everyone nodded numbly, still stunned by his ferocity. "It's all right," he added. "Remember, I'm on your side."

  Around the bend of the tunnel was the opening.

  Ripred made a right turn, and they peeled off in single file behind him. A narrow path led along the side of a canyon. When Gregor shone his light into it, he saw nothing but blackness. "And the fall is immeasurable," he thought.

  The ground under his left foot, the one closest to the void, crumbled and sent a shower of stone and dirt into the darkness. Gregor never heard it hit the bottom. His only consolation was that Aurora and Ares were inching along somewhere behind him, ready to save anyone who fell.

  After about fifty yards they reached the more solid ground that fanned out from one end of the canyon. A natural arch of stone framed a wide road, worn smooth by many rat feet. Ripred picked up speed as they crossed under the arch, and Gregor felt that any protection the terrain had given them was gone.

  Ripred, Temp, Gox, and Gregor raced down the road. Luxa and Henry had instinctively taken to the air. Gregor felt as if rat eyes must be burning at them from every crevice.

  The path ended abruptly at a deep circular pit with walls as smooth as ice. A faint light burned in the pit revealing a furry creature hunched over a stone slab, fiddling with something. At first Gregor raised a warning hand. He thought it was a rat.

  CHAPTER 24

  The man who had disappeared from Gregor's life two years, seven months, and who knew how many days ago had been the picture of health. Strong, tall, and vibrant, energy had seemed to pour right out of him. The man squinting up at them from the pit was so thin and weak, his attempt to stand failed. He fell on all fours, then lifted one hand to help tilt his own head back.

  "Dad?" Gregor tried to say, but all the moisture had left his mouth. He dropped to his own knees at the side of the pit and reached out a hand futilely. They were fifty feet apart, but he reached, anyway.

  Luxa and Henry flew down, helped the pitiful form onto Aurora's back, and carried him up.

  Still on his knees, Gregor clutched his father's hands, once so strong and capable. As he felt the bones beneath his fingers he remembered how his dad used to crack walnuts with his hands. "Dad?" he said, and this time he could be heard. "Dad, it's me. Gregor."

  His father frowned as if trying to remember something. "It's the fever. I'm seeing things again."

  "No, Dad, it's me, I'm here. And Boots is here, too," said Gregor.

  "Boots?" said his dad. He frowned again, and Gregor remembered he had never seen Boots. She had been born after he fell.

  "Margaret," Gregor corrected himself. As soon as his mom was pregnant, his parents had planned to name Boots Margaret after his dad's grandma.

  "Margaret?" said his dad, now thoroughly confused. He rubbed his eyes. "Grandma?"

  The prophecy had named "one lost up ahead," but Gregor had not expected to find his dad as lost as this. He was skeletal and weak -- and what had happened to his hair and beard? They were snow white. Gregor touched his father's shoulder and realized he was wearing a cloak made of rat fur. No wonder he had looked like a rat from above.

  "Just want to sleep," said his father vaguely. This was the scariest part of all. Gregor had thought he would get a parent back when he found his dad. Then he could stop having to make hard decisions. He could just be a kid. But the man before him was even needier than Boots was.

  Luxa laid her hand on his dad's cheek and frowned. "He burns like your sister, and he has no strength to fight it. This is why he speaks in confusion."

  "Maybe if I talk to him a minute, he'll remember. He's got to remember, Luxa," said Gregor desperately.

  "We must fly now, Gregor," insisted Luxa, tipping a large swallow from the blue bottle into his dad's mouth. "We shall heal him properly in Regalia. Henry, help me secure him." She tried to tie his dad to Aurora with a length of silk that Gox was rapidly spinning. "Henry?" said Luxa again.

  But Henry stood apart from them. Not helping. Not hurrying. Not even bothering to seem anxious. "No, Luxa, we have no need to hurry now."

  It was a strange answer. No one understood what he was saying except Ripred. An odd look crossed the rat's face. "No, I believe Henry has taken care of everything."

  "Henry had to," said Henry. He lifted his fingers to his lips and gave a long whistle.

  "Are you crazy? What are you doing?" asked Gregor. He looked at Luxa, who seemed to have turned to marble. The silk rope slipped from her hands and fell to the ground.

  The patter of many rat feet came at them down the road. What was going on? What had Henry done?

  "Ripred?" said Gregor.

  "It seems I am not the only spy among us, Overlander," said Ripred wryly. "A member of the royal family, too."

  "You mean, Henry ...?" Gregor would never in a million years have believed Henry to be a spy for the rats. They had killed his parents, his people. "He can't be," blurted out Gregor. "He can't, I mean, what about Luxa?" The two were so tight.

  "Sorry, cousin," said Henry urgently to Luxa. "But I had no choice. We were headed for disaster under Vikus. He would ally us to the weakest, when our only real chance of survival is to ally ourselves with those who are most powerful. We will join forces with the rats and rule together, you and I."

  Luxa spoke more calmly than Gregor had ever heard her. "Not now, Henry. Not ever."

  "You must, Luxa, you have no choice. You must join with us or die," said Henry coldly, but there was a tremor in his voice.

  "This is as good a day as any," said Luxa. "Perhaps better." She sounded a thousand years old and a thousand miles away, but she did not sound scared.

  "So they promised you a throne, did they? Really, Henry, you are not fool enough to believe they will deliver it," said Ripred, breaking into a laugh..

  "They will deliver it. Together we will rid the Underland of crawlers and spinners and share their land among us," said Henry.

  "But why? Why would you do that?" asked Gregor.

  "I am tired of having cowards and weaklings as allies," said Henry. "The rats, at least, are not guilty of that. Together, we will protect each other. Together, we will rule. Together, we will be safe. It has been decided."

  "Together, together," said Ripred in a singsong voice. "What a lot of togetherness you are planning. And what a lot of solitude awaits you. Ah, here are your friends now."

  There were at least fifty of them. The rats fanned out quickly and circled the questers. Most of them were laughing, delighted at the rich catch before them.

  Gregor's eyes darted around. Who would fight on his side? His dad was mumbling something about fish. Boots lay tied to Temp's back, oblivious to the world. Henry was a traitor, so he could count Ares out, too, since the pair was bonded. That left him, Luxa, Aurora, Gox, and ... suddenly he didn't know what to think of Ripred. What about Ripred? Whose side was the rat really on?

  He looked at Ripred, and the rat gave him a slow wink. "Remember, Gregor, the prophecy calls for only four
of the twelve to die. Think we can take them, you and I?"

  Okay, he also had one amazing rat on his side.

  The circle widened, leaving a gap. A huge silver rat strode into the space. Jammed over one ear was a gold crown, clearly designed for a human head. Gregor heard Luxa inhale sharply and guessed it had belonged to one of her parents.

  "King Gorger," said Ripred, giving a low bow. "I did not hope we would have the honor of your presence here."

  "An unfortunate crawler told us you drowned, Ripred," said the king in a low voice.

  "Yes, well, that was the plan," said Ripred, nodding. "But so often plans go awry."

  "We must thank you for bringing the warrior so neatly into our paws. It was Henry's job really, but no matter as long as he is here. I wanted to be sure. I wanted to see him for myself before I killed him. So this is he?" asked King Gorger, peering at Gregor. "I expected so much more."

  "Oh, do not judge him too quickly," said Ripred. "I have found him most delightfully full of surprises." He made his way around the circle, occasionally lifting a front leg to scratch his nose. Each time he lifted his paw the rats near him flinched. "Clawsin ... Bloodlet... now break my heart, Razor, is that you? You have no idea how it hurts me to see you in His Majesty's company."

  The rat Razor dropped his eyes away from Ripred's. Was he ashamed? Could rats even feel ashamed?

  Ripred came up behind Henry and nudged him forward. "Go, go, go, go. Stand with your friends." Henry tripped and fell into place beside King Gorger, stepping on his tail. The other rats laughed, but not the king who whipped his tail out from under Henry and slashed poor Gox in half.

  The rats stopped laughing. Gregor saw the spider's blue blood gushing onto the ground. It was that quick. In a split second, a third member of the quest was dead.

  "Why has everyone stopped laughing?" said King Gorger. "Go on, laugh!" he ordered, and the rats let out a sound like sheep bleating. He stretched out on the ground in a pose of complete relaxation, but Gregor could see his muscles were still tense with anger.

  "Who's next?" said King Gorger. "Come, do not be shy. Shall we take care of the pup? She looks soon to expire, anyway." He trained his ratty eyes on Boots.

  "Not Boots," thought Gregor. "Not while I can stand." Something nagged at the back of his brain. What was it? What did it remind him of? And suddenly he knew. He knew what the next part of the prophecy meant.
