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.

Eleven-year-old Willodeen adores creatures of all kinds, but her favourites are the most unlovable beasts in the land - strange beasts known as 'screechers'....

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.

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 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?

Two of the free Hork-Bajir living on Earth have brought the Animorphs and Ax a terrifying discovery: Visser Three has tried—unsuccessfully—to create a race of amphibious Hork-Bajir.

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.

Tobias's worst nightmare has come back to haunt him-Taylor. Taylor is the evil Yeerk that captured and tortured Tobias, trying to get him to reveal the secrets of the Animorphs. Now she's captured him again-but this time, she wants his help.

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.

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.

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....

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....

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....

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....

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....

Tobias has gotten used to his new life. He's a red-tailed hawk with the mind of a kid. It was difficult when he first became trapped in his morph, but he's started to come to terms with things....

Marco and the other Animorphs have managed to find out where the Yeerks are planning to build their next ground-based Kandrona. That's a good thing. But the location is supposed to be somewhere near the North Pole. That's a bad thing....

Dak Hamee is a unique Hork-Bajir. His people call him a seer. He learns more quickly and completely than the rest of his docile race. Hork-Bajir like him are born once a generation.

There's been an accident. Someone crash landed a Yeerk Bug fighter, and the Yeerks have been trying to cover it up - quickly. When Tobias spots it before they get the chance, the Animorphs decide to steal the ship, to show the world that Earth has been invaded....

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!
