Animorphs Volume 1

Earth has been invaded by the evil Yeerks.

The power to save the world lies in the hands of five teenagers - Jake, Rachel, Marco, Cassie, and Tobias - who acquired the ability to morph into any animal they touch, gifted by a dying alien prince.

They must trust no one, and nothing will ever be the same again... Based on the best-selling Scholastic book series.
