The Earth is being invaded, but nobody is aware of it. When Jake, Rachel, Tobias, Cassie, and Marco come across a downed alien spaceship and its own dying pilot, they’re given an incredible power — they are able to transform into any pet they touch. With it, they become Animorphs, the improbable champions within a secret war for the planet. And the foes they’re fighting could be anyone . also the people closest to them.
