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....

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.

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.

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....

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....

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.

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 Yeerks are finally starting to realize that the "Andalite bandits" are probably not aliens at all. That maybe they've been dealing with humans all along. And no one -- especially the newly appointed Visser One -- is happy about this revelation.

The Animorphs have met the Ellimist. He helped to save the kids when they were about to be eaten by a Taxxon. He helped to free two Hork-Bajir and restored Tobias's morphing ability. But even though the Ellimist has enormous power, he is not all powerful....

Really big trouble is an understatement these days. The war with the Yeerks is full on -- and it's definitely going to get worse. But Cassie and the other Animorphs have a lot more going on than just trying to stay alive. Now they've got to actively protect their families and the free Hork-Bajir.

From beloved authors Katherine Applegate and Gennifer Choldenko, Dogtown is an uplifting adventure sure to find a forever home in listeners’ hearts. Dogtown is a shelter for stray dogs, misbehaving dogs, and discarded robot dogs, whose owners have outgrown them. Chance, a real dog, has been in...

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....

Elfangor-Sirinial-Shamtul is an Andalite war prince--the one who gave the Animorphs the power to morph. "The AndaliteChronicles" is the story of how this warrior-cadet ended up on planet Earth.

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 seems to have grown up overnight–literally. When he went to asleep he was his usual kid-self, and when he woke up, about ten years had flown by! What's worse, the Yeerk invasion of Earth has succeeded.

The war between the Yeerks and the Animorphs is still raging. There are no more secrets -- but there are plenty of lies. The kids are fighting harder than they ever thought they could. And they're about to make the biggest decision they've ever had to face.

There's something pretty weird going on in the woods behind Cassie's house, the place where Ax and Tobias call home. It seems the Yeerks have figured out one very important fact: Andalites cannot survive without a feeding ground....

We can't tell you who we are. Or where we live. It's too risky, and we've got to be careful. Really careful. So we don't trust anyone. Because if they find us...well, we just won't let them find us. The thing you should know is that everyone is in really big trouble. Yeah. Even you.

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....

The Yeerks aren't playing around anymore. They're no longer hiding behind a silent invasion. And one of the first steps in their new plan is to take over the National Guard, to prepare for all-out war against humanity.
