The wildly popular series by K.A. Applegate is back! The first six books of Animorphs return, with striking new lenticular covers that morph.

Marco never wanted to be an Animorph. He didn't want the ability to change into any animal he touches. And he certainly didn't want to be one of a handful of kids that are the planet's only defense against a secret alien army. His friends know why he feels the way he does. He's worried about his dad -- the only family Marco has left. If anything happens to him, his father will be alone. But something big is about to change for Marco. Something that could finally give him a reason to fight.
