res insisted Gregor sleep for a few hours. When he woke, they began their trek into the tunnel. It was narrow initially, but soon opened up into a space wide enough for Ares to fly, which was a relief, since Gregor's arms were aching from carrying the Bane.

They stopped to break for a drink at a stream in a cavern.

"Remember you this place?" asked Ares.

"No," said Gregor. "Wait, maybe..." They had stopped here to rest when Ripred was their guide. "Is this where Henry tried to kill Ripred in his sleep?"

"Yes, and you stepped between them," said Ares.

"I couldn't figure out if you knew Henry was going to try to kill him," said Gregor.

"I did not. It was one of many things Henry neglected to mention to me," said Ares. Gregor could tell he didn't want to talk about it anymore.

As they flew on, the Bane began to whimper for its mother again. How bizarre this must all seem to the baby rat. Flying through the air on a bat, being held by a human, knowing something very wrong had happened to its mother. Gregor fed it the rest of the chocolate bar from the Labyrinth. He had one left but decided to save it for a real emergency.

The smell of rotten eggs began to permeate the tunnel, and Gregor knew that they were fast approaching the cavern where they had first encountered the spiders, Treflex and Gox. Ares landed at the entrance, and they went in on foot. The sulfur-scented water still rained down the walls. There, on the floor, was the husk of Treflex's body, all that remained of the spider after his companion, Gox, had drained his insides.

"Want to rest?" asked Gregor.

"Not here," said Ares.

"Good," Gregor said, even though what lay ahead was nasty.

The tunnel dripped the evil-smelling water down on them. Ripred had taken them through it with the idea of concealing their scent from the rats, and they had certainly reeked of rotten eggs when they came out. This trip was, if possible, less comfortable. Gregor had been wearing a hard hat the first trip, which had offered some protection. He had not been injured. He had been eager to find his father instead of dreading the moment when they next met. And he had been carrying Boots on his back, not a rat in his arms.

Poor Ares had ridden on Temp's back before, because the tunnel was so narrow and long. Now he limped along, scraping his wings on stone outcroppings, ducking his head in the eye-stinging drizzle.

In minutes, they were all soaked. The rat mewed miserably. Gregor trudged along, putting one foot in front of the other. He and Ares did not speak the entire time they were in the tunnel, although it was many hours.

When eventually they staggered out of the mouth into open space, Gregor's knees gave way under him and he sat on the ground hard. He expected the Bane, who'd been squirming for most of the trip, to try to run off. Instead, it burrowed up under his shirt and pressed against his chest.

Ares slumped against a rock next to him.

"Are there rats around?" asked Gregor.

"About ten are coming now. But that is what we want, right?" said Ares.

"That is what we want," said Gregor.

Neither of them made any attempt to move as the rats surrounded them. And then, he saw the diagonal scar that split Ripred's face.

"If I had known that you were coming, I'd have fixed the place up," said Ripred.

"Don't bother. We won't be here long. I just came to give you a present," said Gregor.

"For me? You shouldn't have," said Ripred.

"You brought me Twitchtip," said Gregor.

"Not because I expected anything in return," said Ripred. His nose was beginning to move; his eyes fastened on the lump under Gregor's shirt.

"You're getting something, anyway," Gregor said, and pulled up his shirt. The Bane slid out on the floor in front of him. Every rat except Ripred gasped. Seeing another rat, the baby started to run to Ripred, but it jumped back at the violent hiss that issued from his mouth and scurried over to Ares.

"You don't like little kids, do you?" said Gregor. Ripred had hissed at Boots, too.

"Not this one in particular," snarled Ripred. "What's it doing here?"

"I didn't know where else to take it," said Gregor.

"You were supposed to kill it!" said Ripred.

"But I didn't. I brought it to you," said Gregor.

"And what makes you think I won't kill it?" said Ripred.

"I don't think you'd kill a pup," said Gregor.

"Ha!" Ripred said, pacing angrily in a circle. Gregor wasn't sure whether that meant yes or no.

"Okay, how about I don't think you'd kill the Bane? Because if you do, you'll never get the other rats to follow you," said Gregor.

It was lucky he'd been sitting down, because Gregor smacked back onto the rock so fast, he would have cracked his skull open if he'd been standing up. As it was, it hurt plenty.

Ripred pinned him to the ground with one paw as he bared his fangs in Gregor's face. "And have you also thought that, under the circumstances, I might very well kill you?"

Gregor swallowed hard. The answer was yes. But instead of admitting it, he looked Ripred dead in the eye and said, "Okay, but I think I'd better warn you that, if we fight, you've only got a fifty-fifty chance of winning."

"I do?" said Ripred. It was enough to distract him for a second. "And why is that?"

"Because I'm a rager, too," said Gregor.

Ripred began to laugh so hard he fell over on his side. The other rats were laughing, too. Gregor didn't even feel like sitting up. "It's true," he said to the ceiling. "Twitchtip smelled it on me. Ask Ares."

No one asked Ares; they were guffawing too hard. That was one thing you had to give the rats: They enjoyed a good joke. Finally Ripred pulled himself together and swept his tail around, shooing the other rats away. "Go," he said. "Leave them to me."

"All right, Rager," he said when they were gone. "Tell me what happened, and don't leave out any details. I left you after our sorry excuse for an echolocation lesson and —"

"And then I ran into Nerissa," said Gregor. He told Ripred everything: about the fireflies and squid tentacles, about saving Twitchtip at the whirlpool and losing Pandora at the island, about the serpents in the Tankard and taking refuge in the cave. And then he found he couldn't go on.

"Yes, you six were in the cave and what about the others?" asked Ripred.

"They were lost," Ares said, after it was clear Gregor wasn't going to answer. And the bat picked up the story, telling how the remaining group had split. How Twitchtip had led them until she'd collapsed. How Goldshard and Snare had fought. How Gregor had taken the Bane. "And now we are here."

Ripred looked at them thoughtfully. "So, you are. What's left of you," he said. "I am sorry for your losses."

That was the thing about Ripred: One minute he was about to kill you, and the next he seemed to understand it was all you could do not to curl up into a ball and die.

"Just out of curiosity, Gregor, what do you expect me to do with that pup if I don't kill it?" said Ripred.

"I thought you might, you know, kind of raise it. Everyone's so afraid of what it's going to turn into. And if Snare had got hold of it, it probably would've grown up to be a monster. But maybe if you take care of it and stuff, it might turn out okay," said Gregor.

"You thought I'd be its daddy?" said Ripred, as if he hadn't heard right.

"Or, at least its teacher. One of the other rats could be its parent," said Gregor. "Just for, you know, eighteen years, or whatever."

"Ah, here's something you obviously don't know about rats," said Ripred. "That ball of fluff over there will be full grown by the time you've seen another winter."

"But...it's just a baby," said Gregor.

"Only humans grow so slowly," said Ares. "It is one of their great weaknesses. The rest of us in the Underland mature as the rats do. Some even more quickly."

"But how do you teach it everything it has to know?" said Gregor.

"Rats learn faster than humans. And what does it really need to know? To eat, to fight, to find a mate, to hate everyone who is not a rat. It doesn't take long to learn these things," said Ripred.

"You know other things," said Gregor. "About what goes on in the Overland, even."

"Well, I've spent a lot of time in your libraries at night," said Ripred.

"You come up and read books?" asked Gregor.

"Read them, eat them, whatever mood strikes me," he said. "All right, Overlander, you may leave the pup with me. I won't kill it, but I can't promise I can teach it much. And you know, there will be hell to pay in Regalia."

"I don't care," said Gregor. "If they think I'm going to do their dirty work, they can think again."

"That's the stuff, Boy. You're a rager. Don't let them push you around," said Ripred.

"I am a rager," said Gregor sheepishly.

"I know. It's just that there are brand-new ragers, and there are old veteran ragers who have fought in countless wars. And you would be...?" said Ripred.

"The first kind," said Gregor. "And I don't even have a sword."

"How's your echolocation coming along?" asked Ripred.

"It's not," said Gregor. "I stink at it."

"But you'll keep practicing, because you have such unflagging confidence in my judgment," said Ripred.

"Okay, Ripred," Gregor said, too tired to get into an argument about the whole worthless echolocation thing. He stood up. "Are you going to be able to handle it? The Bane, I mean?"

"If it's anything like its mother, I'll have my paws full," said Ripred. "But I'll manage."

Gregor went over and patted the baby on the head. "You take care, you hear?" The Bane nuzzled his hand.

"Give it this, when we're gone," Gregor said, handing Ripred the remaining candy bar. "It'll help. Ready, Ares?"

Ares fluttered forward, and Gregor climbed on his back. "Oh, yeah, and about Twitchtip. You'll let her stay if she makes it back, right?"

"Oh, dear. You haven't become attached to Twitchtip, have you?" said Ripred.

"As rats go, she is among our favorites," said Ares.

Ripred grinned. "She can stay if she can drag her pathetic hide back here. Fly you high, you two."

"Run like the river, Ripred," said Gregor.

As they flew off, he looked back over his shoulder. The Bane was sitting next to Ripred, eating the candy bar, paper and all.

Maybe it would work out in the end.
