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....

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....

Marco never wanted to be an Animorph. He didn't want the ability to change into any animal he touches. And he certainly didn't want to be one of a handful of kids that are the planet's only defense against a secret alien army. His friends know why he feels the way he does....

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'....

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....

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....

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....

We never should have done it. But we needed a break. Some time off from the superhero stuff. A chance to act like normal kids. Well - as normal as four kids who can morph into animals, a boy trapped in a hawk's body, and a bright blue alien can be.

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....

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....

Rachel's got some pretty strange stuff happening. She can't control her morphing. One minute, she's doing homework. The next, she's morphing a full-grown crocodile, and - without returning to human form - she becomes an elephant....

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.

From the Newbery Award-winning and bestselling author of the modern classic One and Only series comes a gorgeous picture book introducing young listeners to Ruby, the beloved baby elephant.

Bob sets out on a dangerous journey in search of his long-lost sister with the help of his two best friends, Ivan and Ruby. As a hurricane approaches and time is running out, Bob finds courage he never knew he had and learns the true meaning of friendship and family....

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.

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.

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.

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....

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.

Ivan has been happily living in a wildlife sanctuary, with his friend Ruby next door in the elephant enclosure, frequent visits from his canine friend Bob, and his mate Kinyani by his side....
