HEY! What are you guys doing? We're going to metamorphosize. Meta-WHAT-now? Transform into butterflies. Right. Right. I knew that... WAIT?! You're telling me I can become a BUTTERFLY? Yes. With wings? Yes. Wait for ME!! Ross Burach's hilarious, tongue-in-cheek exploration of metamorphosis will make you flutter with glee, while also providing real facts about how caterpillars transform into butterflies.

The Animorphs, Jake and Ax steal a Yeerk Bug fighter and end up in another time and another place, with no way home.

When Jake, Rachel, Tobias, Cassie, and Marco stumble upon a downed alien spaceship and its dying pilot, they're given an incredible power ... a power they must use to outsmart an evil greater than anything the world has ever seen.

The Animorphs have to make the most important decision they've ever faced: Do they continue to fight the Yeerks in secret, or is it time to let everyone know there's a resistance?

And Ax is dying. Cassie and the other Animorphs come up with a plan. But it involves finding a new way into the Yeerk pool. There's just one problem: Jake, Rachel, Tobias, and Marco all come down with Ax's sickness. And now, for the first time, Cassie is on her...

It seems a human-Controller named Karen followed Cassie after the last run-in with the Yeerks, and she knows Cassie has the ability to morph. If she exposes Cassie, it's all over. No more Cassie. No more Animorphs....
