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 try and 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 if anything goes wrong, it's all over...
There is a new Animorph. And he's arrived just in time, because the Yeerks are preparing their biggest takeover ever. The ultimate target: the world's most powerful leaders gathered together in one place. What better way to get into the minds of humans? Literally At first, David joins the fight with a vengeance. But there is definitely something wrong. Because he's starting to break the rules. Taking risks that could get them all captured. Or killed. The Animorphs don't know what to do. Because there was a time when the Yeerks were their greatest enemy. That's about to change...
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 near 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 near the North Pole without Arctic morphs -- and wearing spandex? Even so, the kids know that 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's made a pretty amazing discovery. It seems like there may be other people who know about the invasion. Others who know about the Yeerks. Jake finds a Web site devoted to the Yeerks. And Jake, the other Animorphs, and Ax aren't sure it's too good to be true. But if they try to investigate the site and it's a trap, there's no way the Yeerks won't find out who they are. If they don't check it out, they'll never know if they're the only ones fighting. Whatever Jake and the others decide to do, they've got to move quickly, because Visser Three isn't the only one dying to meet them...
What's tasty, good for you, and only takes sixty seconds to make? Oatmeal. And it's making the Yeerks more than a little crazy. Now Rachel, the other Animorphs, and Ax have a new weapon against the Yeerks. Sounds good, right? Wrong. Because it means another trip to the Yeerk pool. And the possibility of running into Visser Three. And of not being able to get back up to the surface. The Animorphs and Ax have taken chances before and been very lucky. But this time their luck may be about to run out...
