David, the newest Animorph, is not what he appears. His need to control the other Animorphs is all he thinks about. And the things he does are starting to break up the group....

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 pint-sized Helmacrons may have departed Earth, but they haven't finished causing trouble for the Animorphs and Ax. They left behind a damaged ship—containing morph-tracking technology. Now the Yeerks have found the ship, and are launching a full scale Animorphs hunt....

Ax and the Animorphs are about to have a huge problem. It starts when they decide to morph into mosquitoes in order to slip by some unsuspecting Yeerks, and ends with them stuck in Zero-space with no idea how they got there, no way back to Earth...and no oxygen....

There is an Anti-morphing ray out there. It's purpose: to cause a person in morph to revert to his natural form. And the Yeerks have done a very good job in hiding it. Word from the Chee that the Yeerks are ready to test the weapon. Just one problem: They don't have a test subject.

The second audiobook in #1 New York Times bestselling author Katherine Applegate's fun new series. Doggo likes routine: napping, eating, and more napping. Life is good. Life is good for Pupper, too, even though he worries a lot, about things like giant squirrels. If he were braver, he might even...

There is a new Animorph. And he's arrived just in time, because the Yeerks are preparing their biggest takeover ever. Their ultimate target: the world's most powerful leaders, all gathered together in one place....

The blue box Elfangor used to create the Animorphs has been found by a kid named David. David has no idea what he has - or what it can do. But Marco does. And when he sees David with it, he knows the Animorphs have to get that box. At any cost....

Cassie's had it. After the last mission, she realizes she's getting tired of missions. Tired of battles. Tired of being an Animorph. She decides that she just can't do it anymore. So she quits. But the war for her planet isn't so easy to quit....

We found out who Visser Four is. And he has found the Time Matrix, the machine Elfangor had hidden in the abandoned construction site. The same place we met him on a night none of us will ever forget. Especially me. Now Visser Four has the Matrix, and he plans to use it to become Visser One....

Things were already really weird. Fighting aliens. Battling to have Earth. And still trying to be normal. Marco and the other Animorphs are almost used to it. But things are changing. The Yeerk invasion of Earth started out passively, secretly.

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? That the Animorphs exist and Earth does stand a small chance against the invasion.

David, the traitorous Animorph, is back. When the Animorphs decided to give another human being the power to morph, it was one of their biggest mistakes.

The Animorphs have managed to contact the Andalite home world, but the battle is far from over. Visser Two has arrived on Earth, and he's not happy about the state of things.

The Andalites have returned! The main fleet flew off-course in an effort to stop the galaxy's newest threat – the Rakkam Garoo. But a small crew managed to reach Earth. Now it's up to the Animorphs to decide how to treat their new allies. Can the group be trusted?

Jake has to attend a wedding out of town. No one has been designated to take over as leader of the Animorphs. But when Tobias tells the others that he's found the place where Visser Three currently feeds, there is a unanimous agreement on going after him.

Everyone thought Visser Three and Ax were the only Andalites on Earth–until now. The Animorphs have discovered two other warriors who escaped from Ax's Dome ship, and they may be able to help fight against the Yeerks!

Cassie is on her own. There's no Jake to lead the mission. No Marco to tell stupid jokes. And no Rachel to say "Let's do it!" It's just Cassie. Alone. In Australia. It all began when the latest Animorphs' mission took a bad turn–and Cassie hid in the cargo hold of a jumbo jet.

The Yeerks have decided to step-up recruitment in The Sharing---but it's not going to be celebrity endorsements this time. It's a cable TV show, one with a lot of interactivity: call-in and Web site....

Jake and Tom's maternal great-grandfather dies suddenly. Their mom immediately travels out of state to help make arrangements for the funeral. Jake, Tom, and their father are to follow in two days when their dad can take off from work....
