If someone told you that aliens were invading the planet, you'd probably think they were crazy, right? Well, it's true. The most deadly enemy the world has ever encountered is here. And they could be anyone. Your teacher, your sister, your neighbor, your best friend. Anyone.
They live in your head. They slither into your head through your ear canal and take complete control. They control your every move, your every word. You are a slave to the alien slug in your head. You are trapped in the corner of your mind, and all you can do is scream as the Yeerk in your head betrays everyone you love.
Scared yet? It gets worse.
Guess who's defending the human race against these deadly parasites? Not the army, or the national guard. Five human kids and an alien. Yes, that's right. Five not-so-normal human kids and one Andalite child.
But there's still hope for Earth, because these kids have one powerful weapon in this war with the Yeerds. The power to morph. The power to change into any animal they can touch. For two hours at a time, the kids can become a lion, a wolf, a hawk, an eagle, a dolphin, or anything else, by absorbing it's DNA.
With this weapon, they fight for our freedom.
Animorphs.
