"If you wish, I can give you powers that no other human being has ever had."

"Powers?" What was that supposed to mean?

"It is a piece of Andalite technology that the Yeerks do not have," the Andalite explained.

"A technology that enables us to pass unnoticed in many parts of the universe - the power to morph. We have never shared this power. But your need is great."

"Morph? Morph how?" Rachel asked, her eyes narrowed.

"To change your bodies," the Andalite said. "To become any other species. Any animal." Marco laughed derisively. "Become animals?" Marco isn't the most accepting person in the world, "You will only need to touch a creature, to acquire its DNA pattern, and you will be able to become that creature. It requires concentration and determination, but, if you are strong, you can do it. There are . . . limitations. Problems. Dangers, even. But there is no time to explain it all . . . no time. You will have to learn for yourselves. But first, do you wish to receive this power?"

"He's kidding, right?" Marco asked me.

"No," Tobias said softly. "He's not kidding."

12 "This is nuts," Marco said. "This whole thing is nuts. Yeerks and spaceships and slugs taking over people's brains and Andalites and the power to change into animals? Give me a break."

"Yeah, it is beyond weird," I agreed.

"We're off the map of weirdness by this point," Rachel said. "But unless we're all just dreaming, I think we'd better deal with this."

"He's dying," Tobias reminded us.

"I'll do it," Cassie said. That surprised me. Cassie isn't usually so quick to decide. But I guess, like Tobias, she felt the truth of what the Andalite was saying.

"I think we should all decide together," I suggested. "One way or the other."

"What's that?" Rachel asked. She was looking up toward the stars. Far, far overhead, two pinpoints of bright red light were shooting across the sky.

"Yeerks." The Andalite said the word in our minds, and we could feel his hatred.

13 CHAPTER 4

"Yeerks!"

The twin red lights slowed. They turned in a circle and came back toward us.

"There is no more time. You must decide!"

"We have to do this," Tobias said. "How else can we fight these Controllers?"

"This is so insane!" Marco said. "Insane."

"I'd like more time, but we don't have that choice," Rachel said. I'm for it."

"What do you say, Jake?" Cassie asked me. It was odd. Like suddenly I was the one who had to decide for everyone?

I looked up at the Yeerk ships. What had the Andalite called them? Bug fighters? They were circling closer, like dogs sniffing for a scent. I looked down at the Andalite and remembered the picture of his family. Would they even know what had happened to him?

I looked at each of the people around me - my usually funny, occasionally annoying best friend, Marco; Rachel, my smart, pretty, confident cousin; and Cassie, who everyone knew liked animals more than she liked most people.

Finally, I looked at Tobias. It was weird, the feeling I had at that moment, staring at him. A chill or something.

"We have to," Tobias said to me.

Slowly I nodded. "Yes. We have no choice."

"Then each of you, press your hand against one of the sides of the square." We did. Five hands, each pressed against one side. Then a sixth hand, different from ours, with too many fingers.

"Do not be afraid," the Andalite said.

Something like a shock, only pleasurable, seemed to run through me. A tingle that almost made me laugh.

"Go now," the Andalite said. "Only remember this - never remain in animal form for more than two of your Earth hours. Never! That is the greatest danger of the morphing! If you stay longer than two hours you will be trapped, unable to return to human form."

"Two hours," I repeated.

Suddenly some new fear washed through the Andalite's mind. Linked as I was to him, I could feel it as a dread that crawled up my spine. He was staring up at the sky with his main eyes.

Something else was up there with the Bug fighters.

14 "Visser Three! He comes."

"What?" I was shaking with this new terror. "What's a Visser? Who's a Visser?"

"Go now. Run! Visser Three is here. He is the most deadly of your enemies. Of all Yeerks he alone has the power to morph, The same power you now have. Run!"

"No, we'll stay with you," Rachel said firmly. "Maybe we can help."

Again it was as if the alien was smiling at us with his eyes. "No. You must save yourselves.

Save yourselves and save your planet! The Yeerks are here."

We all looked up, craning our necks. Sure enough, the two red lights were sinking toward us.

And they had been joined by a third ship, far larger, black as a shadow within a shadow.

"But how are we supposed to fight these . . . these Controllers?" Rachel demanded.

"You must find a way. Now run!"

I jerked from the force of his command. "He's right. Run!" I yelled.

We ran. All but Tobias, who knelt beside the Andalite and took his hand. The Andalite pressed his other hand against Tobias's head. Tobias rocked back, like he'd been shocked.

Then he, too, was up and running, stumbling over the loose junk and potholes of the construction site.

A beam of bright red light snapped on. It was a spotlight from one of the Bug fighters. The beam lit up the fallen Andalite and his ship. A spotlight from the second Bug fighter joined the first, and the Andalite shone brilliant as a star.

I hit the dirt hard. I saw my leg lit up within the circle of that spotlight. I yanked it to me and crawled fast, scraping my elbows and knees over sharp stones.

The five of us crouched behind a low, crumbled wall, afraid to move, afraid to look, but just as afraid to look away.

Slowly the Bug fighters descended. It was easy to see where they'd gotten their nickname.

They were slightly larger than the Andalite fighter and shaped like legless cockroaches.

There were small windows like eyes on the forward-thrust head of the bug. And on either side of the head were two very long, very sharp, serrated spears.

The Yeerk Bug fighters touched down, one on either side of the Andalite ship.

"Okay, you can wake me up now," Marco said in a rattled whisper. "I've had enough of this dream."

The larger ship began to descend. I don't know what it was about that ship, but as it got closer I started to feel like I couldn't breathe. I tried to suck in a deep lungful of air and couldn't. I tried to swallow and couldn't. I wanted to run, but my legs were jelly. I was shaking from a fear so deep it was like nothing I'd ever experienced before. It was the same fear that the Andalite had shown when he'd realized Visser Three was coming.

15 The ship settled toward the ground. It looked like it was going to land directly on a big rusted earthmover parked there. But as the Visser's ship descended, the earthmover just sizzled and disappeared.

Visser Three's ship was built like some ancient weapon. It reminded me of one of those battle-axes the old-time knights used when they were hacking off the heads of their foes.

There was a main part, like the handle of the ax, with a big, triangular point on the front. That part had to be the bridge. At the rear were two huge, scimitar wings. It was eight or ten times the size of the Bug fighters.
