The Yeerks are finally starting to realize that the "Andalite bandits" are probably not aliens at all. That maybe they've been dealing with humans all along. And no one - especially the newly appointed Visser One - is happy about this revelation. When Tobias and the other Animorphs realize that the Yeerks are about to find them, it's by accident. But that doesn't make the discovery any less serious. Because in a war, one side wins and one side loses......

Really big trouble is an understatement these days. The war with the Yeerks is full on -and it's definitely going to get worse. But Cassie and the other Animorphs have a lot more going on than just trying to stay alive. Now they've got to actively protect their families and the free Hork-Bajir. And they no longer believe they can do it alone. The Yeerks are just too powerful. So Cassie and the others have to ask themselves a very important question:...

When Tobias discovers a new alien feeding place while Jake is away, he and the other Animorphs determine to do something about it, but without a designated leader they find the project more difficult than they expect.

He is called the Ellimist. A being with the ability to alter space and time. A being with a power that will never be fully understood. He is the reason Elfangor came to Earth. He is the reason the Earth now has a fighting chance. And though his actions never seem quite right or wrong, you can be certain they are never, ever what anyone expects.

This is the beginning and the middle of the story. A story that needs to be told in order to understand

...

Using their infamous cockroach morphs, Rachel, Marco, and Tobias gain entry into an alien enemy's underground city and find themselves in danger of becoming alien snacks when an omnipotnet Ellimist arrives on the scene.
