"Earth has definitely changed since the Rock hit it 500 years ago. The world doesn't even revolve anymore. On one side: an unbearably hot, arid, unyielding desert with boiling seas and no relief. On the other: a vast, pock-marked plain of freezing-cold eternal darkness. The Remnants are trapped in a narrow strip between the two deadly plains, with nowhere else to go.
"But there is more to this devastated Earth than meets the Remnants' eyes. There are people underground. Humans. And they've been watching Jobs and the others' every move. Now the question is: Will Earth's current inhabitants accept those from the past? Or will the Remnants become as extinct as the planet they once knew?"

Now they have to find Senna and get home without losing their lives. Or their minds. Or both . . . "

"It was really bad when Jake found out his older brother was one of them. It was even worse when Tobias stayed in his morph too long. But nothing compares to the horror the Animorphs are about to face. Nothing. Jake, Rachel, Tobias, Cassie, and Marco have a feeling they know where the Yeerks’ new base is located. And they’ve even figured out how to get in—how many people will really notice a few flies on the wall? But they never figured that they might get caught. Or that Jake could fall into the Yeerk pool. That Jake could become a human-Controller. A Yeerk. The enemy."

In another state. For three or four days. This is a very big problem for Jake’s brother, Tom. He can’t be away from the Yeerk pool for that long. So Tom refuses to go - and his father insists. But Tom’s Yeerk will do anything to survive. Including making his father less of a problem.

"Almost nothing could be as bad as finding out your mother is Visser One. The most powerful of all Vissers. The leader of the Yeerk invasion of Earth. But it happened to Marco. And even though he’s been handling it pretty well, he knew there’d come a time when he’d have to face her again. Knowing that the Yeerk in her brain had taken his mother away. So when Marco, the other Animorphs, and Ax discover that Visser One is overseeing a secret underwater project, they know they have to check it out. But Marco’s not sure if this is a battle he’ll be able to fight."

"The Yeerks have decided to try a little experiment. They’ve decided that if they can develop a way to make people more ‘willing’ to be infested, they can speed up Earth’s invasion. So, the Yeerks try to invent a substance that will take away the human ability to make a decision. A substance that will eliminate free will. Now the Animorphs and Ax are not only faced with trying to slow down the Yeerks’ invasion, but they also have to put an end to the genetic testing on a small group of humans. This time there’s only one chance to stop the Yeerks. And it anything goes wrong, it’s all over."

"Marco, the other Animorphs, and Ax have managed to find out where the Yeerks are planning to build their next ground-based Kandrona. That's a good thing. The location is supposed to be somewhere around the North Pole. That's a bad thing. The Animorphs and Ax know that the Yeerks are a 'cold-blooded' species, but this is a little nuts! Who wants to be anywhere near the North Pole without Arctic morphs-and wearing spandex? Even so, the kids know if the Yeerks succeed with their plan, Earth is pretty much done for. And Marco, the other Animorphs, and Ax aren't quite ready to give up the fight."

"Jake is just a normal kid. Well, as normal as possible considering he can morph animals, and he's in a war against parasitic aliens. But as unbelievable as it sounds, something even stranger has happened. One morning Jake wakes up, and he's twenty-five years old. Okay. Maybe it's some kind of weird hallucination. Maybe it's a nightmare. Or maybe Jake's just lost it for a while and misplaced a few years. And there's another problem. The world Jake-the kid went to sleep in has changed. It's ruled by the Yeerks. Jake has to find out if the other Animorphs and Ax are still around. Still somehow fighting. Or if he's really on his own."
