The Beginning (Animorphs #54)

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. Yeerk ships are pouring in from all ends of the galaxy-this is it. What will be the climactic, awful battle the Animorphs have been waiting for. Rachel has always been prepared for all out war, perhaps a little too ready. The President of the United States is a Controller, so the Animorphs have to rally their own military force. They succeed. Five thousand troops will fight against the seemingly endless onslaught of Yeerks. And this time, there will be no compromise. No half way. It's all out war for the Animorphs. It's Rachel's moment.
