The InvasionBy K. A. Applegate
The wildly popular series by K.A. Applegate is back! The first six books of Animorphs return, with striking new lenticular covers that morph. The Earth is being invaded, but no one knows about it. When Jake, Rachel, Tobias, Cassie, and Marco stumble upon a downed alien spaceship and its dying pilot, they're given an incredible power -- they can transform into any animal they touch. With it, they become Animorphs, the unlikely champions in a secret war for the planet. And the enemies they're fighting could be anyone, even the people closest to them. So begins K.A. Applegate's epic series about five normal kids with a limitless amount of forms and abilities.
