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.
Cassie, the other Animorphs, and Ax have a few little problems. A few very little problems. Actually, the problems call themselves Helmacrons. They're less than two and a half centimetres tall, and they're pretty upset at Cassie. They believe she stole their ship. Cassie thought it was just a toy, and gave it to charity. Now the Helmacrons want it back.
So the Animorphs and Ax have a new dilemma. Because the Helmacrons have their own secret weapon: They can shrink other beings down to their size. And, if they don't get their ship back soon, everyone on the planet is in for a little surprise . . .
