We can't tell you who we are. Or where we live. It's too risky, and we've got to be careful. Really careful. So we don't trust anyone. Because if they find us . . . well, we just won't let them find us. The thing you should know is that everyone is in really big trouble. Yeah. Even you.
What would you do if you were the only alien trapped on a strange planet? Probably freak out, right? But as an Andalite warrior-cadet, Ax has to be pretty cool about stuff like that. He's been hanging with the Animorphs ever since the Dome ship was destroyed by the Yeerks and his brother, Prince Elfangor, was destroyed by Visser Three.
Life on Earth is pretty different for Ax. But there is one thing he, Cassie, Marco, Jake, Rachel and Tobias have in common. Something that one alien, four kids, and a hawk know they have to do: stop the Yeerks . . .
