Katherine A. Applegate

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....

Ivan is an easygoing gorilla who has spent his life performing for the crowds at the Exit 8 shopping mall. He rarely misses life in the jungle. In fact, he hardly thinks about it at all....

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....

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.

Meet Odder, the queen of play. Nobody has her moves. She doesn’t just swim to the bottom, she dive-bombs. She doesn’t just somersault, she triple-doughnuts. She doesn’t just ride the waves, she makes them....

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....

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 Animorphs have one true ally in their battle against the Yeerks: the sentient androids known as the Chee. So when they discover that the Chee—including their friend Erek—are in trouble, they have no choice but to help.

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....

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.

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!

Rachel is falling apart. Literally. Her newest morph has the ability to regenerate its limbs, but when Rachel demorphs there's a lot more Rachel than when she started out. One more Rachel, to be exact....

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....

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.

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....

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....

From beloved powerhouse author Katherine Applegate comes The One and Only Ruby, starring the adorable baby elephant from the Newbery Medal-winning modern classic The One and Only Ivan and its bestselling sequel, The One and Only Bob....

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.

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.
