Ivan is an easygoing gorilla. Living at the Exit 8 Big Top Mall and Video Arcade, he has grown accustomed to humans watching him through the glass walls of his domain....

To learn if she truly is the last dairne in the world - the endling - Byx and her friends must travel into the snow-covered mountains of the country of Dreyland, where they hope to uncover the truth behind the legend of a hidden dairne colony....

It all started with the dreams. But Cassie didn't pay much attention to them. She and her friends have been having nightmares ever since they acquired the power to morph....

Rachel is still reeling from the news that the Earth is secretly under attack by parasitic aliens known as the Yeerks. And that she and her friends are the planet's only defense....

The last time Rachel and her friends entered the giant Yeerk pool beneath their town things went very bad. This time they plan to be careful, and sneak in as roaches, just to spy. Once they're inside, though, the team gets caught....

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....

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....

Ax is an Andalite, an alien, stranded on a strange planet he's sworn to defend, even though it's not his own. Since the Animorphs rescued him, he's fought at their side, and in that time they've come to consider Ax a friend. But deep inside, Ax knows he isn't their friend....

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'....

When Tobias and his friends were given the power to morph, they were also given an important warning: Never stay in a morph for more than two hours. But Tobias broke the time limit, and now he's trapped in the body of a hawk - forever....

When Marco runs into his old friend Erek, he doesn't think too much of it. He's got more important things to do, like helping to save the world. But then Marco finds out Erek's been hanging with some of the kids at the Sharing....

Byx is the youngest member of her dairne pack. Believed to possess remarkable abilities, her mythical doglike species has been hunted to near extinction in the war-torn kingdom of Nedarra.

Byx and her new friends soon learned that it wasn’t just dairnes in jeopardy of extinction, but that everyone was at risk. With the world in unprecedented danger, Byx must rally creatures of all kinds to lead a revolution....

It was bad when Jake found out his brother was one of them. A Human-Controller. A slave. But that was nothing compared to this. When the Animorphs decide to visit the Yeerks' new base, it seems simple....

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....

There's a new rumor in town. Someone has discovered an item that proves life on other planets exists, and they've been hiding it on a base called Zone 91, the most secret place on Earth....

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!

Someone's looking for Tobias. Someone who says she's his long-lost cousin. Tobias isn't sure the person is telling the truth, but she's really nice, and knows a lot about him. And what she tells Tobias definitely gets his attention....

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 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.
