Ax and the Animorphs find new hope when they learn that he is not the only non-infected Andalite on Earth.

What would you do if you were the only alien trapped on a strange planet? Probably freak out, right? Well, that's what Ax feels like doing. But as an Andalite warrior-cadet, he has to be pretty cool about stuff like that. He's been hanging out with the Animorphs ever since the Dome ship was destroyed by the Yeerks and his brother, Prince Elfangor, was destroyed by Visser Three. Life on Earth is pretty different for Ax. But there is one thing he, Cassie, Marco, Jake, Rachel, and Tobias have in common. Something that one alien, four kids and a hawk know they have to do: stop the Yeerks...

Morphing is certainly more fun than Sega -- you can soar as an eagle and walk as a cat. But being an ANIMORPH is by no means just fun and games. Rachel knew better than anyone. One of her best friends, Melissa, is acting very strange. And it looks like Melissa's dad, who is also the school's Assistant Principal, may be connected to evil aliens. Rachel can't tell Melissa what the ANIMORPHS have learned, but Melissa doesn't seem interested in talking to Rachel these days anyway. Could Melissa be one of "them?" With the help of Jake, Cassie, Tobias and Marco, Rachel plans to enter her friend's house as a cat, intent on unlocking the secrets from within. If only Rachel could keep her mind off mice...

Ax's people have arrived on Earth, and they want Ax back on board with them. Ax is torn. Should he join his fellow Andalites? Can he desert the Animorphs?

Jake has made an amazing discovery: a Web site about the Yeerks. Should the Animorphs investigate? If they do, they might walk right into a trap. And if they don't, they'll never know if they're fighting their enemies alone...

The Ellimist has helped the Animorphs many times. He is all-powerful and has only one enemy, the Crayak. In a cosmic showdown, the two enemies choose champions to represent them in a battle to end all battles. The Crayak chooses the dreaded Howlers. The Ellimist chooses the Animorphs.

The Animorphs' alien friend Ax is in trouble. He's come down with a virus called "yamphut", and it's making him very sick. The Animorphs discover the virus could be deadly--but they can't take an "alien" to the hospital. They need to come up with a plan--or lose their friend forever.

Almost nothing could be as bad as finding out your mother is Visser One. The most powerful of all Vissers. The leader of the Yeerk invasion of Earth. But it happened to Marco. And even though he's been handling it pretty well, he knew there'd come a time when he'd have to face her again. Knowing that the Yeerk in her brain had taken his mother away. So when Marco, the other Animorphs, and Ax discover that Visser One is overseeing a secret underwater project, they know they have to check it out. But Marco's not sure if this is a battle he'll be able to fight....

While Jake is away at an out-of-town wedding, Tobias discovers the place where Visser Three feeds. There is a unanimous decision to acquire cheetah morphs and run him down. But which Animorph will lead the mission in Jake's absence?

Dak Hamee, born into the Hork-Bajir tribe, is something special from the start. "Strange," says his mother. "A seer," says the Old One, Tila Fashat. "A seer is one who is born to show a new way. Many, many seasons pass, then our father, the Deep, and our mother, the Sky, say, 'Send a seer to the people. The people have need.' And so one is born who is different." When strange and different Dak meets Aldrea, the clever Andalite daughter of Prince Seerow, they learn together of the dangerous plot of the Yeerks, and of Esplin 9466, who will stop at nothing to build his empire. Learn more about Prince Seerow's Kindness, find out how Andalites kiss, and plumb the mysteries of the Deep in this suspense-filled story of good, evil, and interspecies love. (Ages 9 to 12)

We could blame everything that happened on Marco. He was the one who heard about the downed submarine. He was the one who thought we should check it out. And everyone knows that if Marco's up to a challenge, I'm definitely there. Everything was going fine. Until the explosion. An explosion that blows us millions of years back in time. Back to the age of dinosaurs. Now Tobias, Cassie, Marco, Ax, Jake and I are fighting for our lives with every step we take. But that's not our biggest problem. Our biggest problem is we have no idea how to get back to our own time ...

The wildly popular series by K.A. Applegate is back! The first six books of Animorphs return, with striking new lenticular covers that morph. 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. But when Cassie discovers that Tobias has been having dreams too -- the exact same dreams -- about the ocean, and a voice that's calling to them for help, she decides it's time to start listening. Now she and the others have to figure out if the dreams are a message, or a trap.

To rescue their android friends, the Chee, the Animorphs must use a giant squid morph to get to the Chee ship deep in a trench beneath the ocean. And they must reach the ship before Visser Three does.

Cassie's losing her mind. But she's gaining the mind of another. Aldrea -- daughter of Seerow, Andalite Prince. Aldrea's persona, her memory, and a valuable bit of information now belong to Cassie.
