Animorphs. Main series

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

Cassie didn't pay much attention to the dreams. 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 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.

Attempting to get more information about the Yeerks, Jake is suddenly taken over by one of the parasitic aliens and becomes one of them, and the Animorphs launch a rescue mission.

The wildly popular books by K.A. Applegate are back! The Animorphs return in this update of the classic series. 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. He can't ever be. Andalites must always hold themselves apart, even...

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, and he starts to think that something just a little weird is going on.So Marco, Jake, and Ax decide to morph and check old Erek out. Just to see if he's been infested with a Yeerk. The good news is that Erek's not a human-Controller....

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. That's when the floor gives way and Rachel finds herself looking up at what used to be the kitchen ceiling.What's going on? No one's sure, but Rachel and the other Animorphs have to figure it out -- quickly. Because if...

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. Cassie and the other Animorphs already know about life on other planets. Too well. Their enemies the Yeerks will try to access Zone 91, to find out if what's there will threaten their mission to conquer to the planet. So the Animorphs decide to pay Zone 91 and the...

Jake's made a pretty amazing discovery. It seems like there may be other people who know about the alien invasion of Earth. Others who know about the Yeerks. Jake finds a website devoted to revealing the existence of the Yeerks, but he and the other Animorphs suspect it might be too good to be true.If they try to investigate the site and it's a trap, the Yeerks could find out who they are. If they don't check it out, they'll never know if they're...

Ax and the Animorphs are about to have a huge problem. It starts when they decide to morph mosquitoes in order to slip by some unsuspecting Yeerks, and ends with them stuck in Zero-space with no idea how they got there, no way back to Earth . . . and no oxygen.Luckily, an Andalite scout ship finds them before it's too late. But now Ax is finally with his own people. And he doesn't know if he ever wants to go back to Earth. K.A. APPLEGATE is...

And when he sees David with it, he knows the Animorphs have to get that box. At any cost.But what should have been a simple plan ends up going horribly wrong, leaving David is on the run with the Animorphs. Now they have only two choices: turn David over to the Yeerks or make him an Animorph.Part...

David, the newest Animorph, is not what he appears. His need to control the other Animorphs is all he thinks about. And the things he does are starting to break up the group. Rachel and the others know that time is running out. The newest battle against the Yeerks is the most important one yet. And it's not one that will wait. Winning this fight could mean slowing down the invasion. But no one knows what to do with David. Because the newest Animorph...

Cassie and the other Animorphs have a few little problems. A few very little problems. Actually, the problems call themselves Helmacrons. They're less than an inch tall, and they're pretty upset at Cassie. They believe she stole their ship. Cassie thought it was just a toy and gave it to charity. Now the Helmacrons want it back. So the Animorphs have a new dilemma. Because the Helmacrons have their own secret weapon: They can shrink other beings...

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. He has an enemy. The Crayak. The Crayak and the Ellimist have decided that a battle is necessary to prove their ultimate power. But they don't intend to fight each other. The Ellimist will choose...

The Animorphs and Ax try to slow down the Yeerks' invasion, and also put an end to the genetic testing of a small group of humans.

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. Rachel is an okay person to have around, but two could be considered overkill. Especially two Rachels with completely opposite personalities: one is pathetically weak; one is super strong and super nasty.Now the Animorphs have to figure out a way to...

A single Arn, Quafijinivon, the last member of the race that created the Hork-Bajir has survived. He has seen his entire people wiped out. He has seen the Hork-Bajir enslaved. Now, after a lifetime of planning and plotting, he wants to get his revenge on the Yeerks. And he wants to atone for the problems the Arn have caused. He is old and weak. But he has something the Yeerks have reason to fear: the Ixcila, the mind pattern and persona of Aldrea-Iskillion-Falan....

"Have the kids discovered Atlantis...or is it just another trap?"--back cover.

Andalites have finally arrived on Earth. Ax and the other Animorphs now have allies willing to fight against the Yeerk invasion. But there are only four Andalites. Not nearly enough to defeat thousands of Yeerks. Not enough to stop humans from being infested. Everyone agrees that the battle must continue, but the Andalites don't want to fight alongside humans. They feel their skills will be less than adequate. And they demand that Ax choose a side....

Ax, who has always believed that he is the only non-infested Andalite on Earth, discovers that there are others trying to survive until help finally comes.

Sometimes your worst problems are the ones you can't actually see. Like the Helmacrons. These less-than-an-inch-high aliens are back, and they want the morphing cube more than ever. Obviously Rachel and the other Animorphs can't let them take the cube. But when Rachel tries to stop the Helmacrons from stealing it, Marco gets in the way and ends up with tiny aliens, well, up his nose. Rachel and the others can't let the Helmacrons stay inside Marco's...

The Animorphs have been split up before. And they've had to fight battles without one another. But this time is very different. Not only is Cassie totally alone, she's managed to find herself in Australia. In the rural Outback. The other Animorphs don't even know she's there. Cassie doesn't have any idea where she's going, or if she can even survive the rugged terrain. But she does know she has to get to a town or village and contact her family...

"The animorphs have never met Visser Two. Until now..."

Rachel is captured by David, the sixth Animorph who was once trapped and left on a deserted island. He's back and wants revenge.

The war between the Yeerks and the Animorphs is full on, and it's definitely going to get worse.

The war between the Yeerks and the Animorphs is still raging. There are no more secrets - but there are plenty of lies. The kids are fighting harder than they ever thought they could. And they're about to make the biggest decision they've ever had to face. A decision that may eventually break them all. Ax and the Animorphs know that destroying the Yeerk pool would give them a huge chance to take back Earth. And they've figured out a way to do it....

No one ever thought it would come to this. Jake, Rachel, Tobias, Cassie, Marco, and Ax know that even if they could have warned people in the beginning, no one would have believed their story. A story about an invasion of parasitic aliens. So for all this time, Jake and the other Animorphs have secretly fought a desperate battle. Secretly held the Yeerks at bay. But those days are over. It's come down to the final battle between the Yeerks and...
