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.
Ax and the Animorphs are about to have a huge problem. It starts when they decide to morph mosquitoes in order to slip by some unsuspecting Yeerks. It ends with them stuck in Zero-space with no idea how they got there, no way to get back to Earth . . . and no oxygen.
Luckily, an Andalite scout ship finds them before it's too late. But now Ax is finally with his own people. And he doesn't know if he ever wants to go back to Earth . . .
