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.

It was really bad when Jake found out his older brother was one of them. It was even worse when Tobias stayed in his morph too long. But nothing compares to the horror the Animorphs are about to face.

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.

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...

RL 5 ; 009-012 Ax and the Animorphs have a huge problem when they decide to morph mosquitos to slip by some Yeerks. They end up stuck in Zero-space with no idea how they got there, no way to get back to Earth .. and no oxygen.

The blue box Elfangor used to create the Animorphs has been found by David, but David doesn't know what it is. The Animorphs have to get that box at any cost. David ends up on the run with the Animorphs and Ax, and may become the sixth Animorph.

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.

Cassie and the other Animorphs have a few little problems. A few very little problems. Actually, the problems call themselves Helmacrons.

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...

Marco is faced with a difficult decision when his mother threatens to seize control over Visser One.

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...

Andalites have finally arrived on Earth. The Animorphs and Ax 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 more humans from being infested. Will Ax leave his friends in the Animorphs or stand with his people?

Ax and the Animorphs have always believed Ax was the only non-infested Andalite on Earth. That he alone survived the terrible battle between his people and the Yeerks. Until now. There were other survivors. Other Andalites. And they're here on Earth. Trying to keep a low profile. Trying to find a way to defeat Visser Three. Trying - like Ax and the Animorphs - to stay alive until help finally comes. If help finally comes...

Rachel and Ax must evict the tiny alien Helmacrons from Marco's head and prevent them from stealing the morphing cube.

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 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. He decides the best way to take over Earth is to have the humans destroy each other, exhausting their weapons in the process. He's going to start World War III. Ax and his friends know that Visser Two means business. There are only two ways to keep him from destroying everything...

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

The kids are fighting harder than ever and they are about to make the biggest decision--a decision that may eventually break them all. Ax and the Animorphs have known that the ultimate destruction of the Yeerk pool will give them a huge chance to take back Earth. And they have figured out a way to do it. But there's no way to destroy the pool...
