What would you do if you were the only alien trapped on a strange planet? Probably freak out, right? But as an Andalite warrior-cadet, Ax has to be pretty cool about stuff like that. He's been hanging 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...

Visser Three is still trying to find a way to reach the Pemalite ship. The ship that was hidden thousands of feet below the ocean's surface. A ship containing technology so advanced that is is superior to anything even the Andalites have built. And this time, the Visser plans to find the ship so he can use its power to complete Earth's invasion.

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. So everyone agrees that the battle must continue. But the Andalites don't want to fight alongside humasn. They feel their skills will be less than adequate.

Someone's looking for Tobias. Someone who says she's his long-lost cousin. Tobias isn't sure the person is telling the truth, but she's really nice, and knows a lot about him. And what she tells Tobias definitely gets his attention. It seems a lawyer has discovered Tobias's father's last will and testament. So, Tobias needs to attend the reading. His cousin even offers to go along. But something just doesn't feel quite right. That's when Tobias and...

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...

Jake's grandfather has died. It blows the family away, especially Jake's mom. His parents decide they should all travel to his grandfather's home to help with the arrangements. In another state. For three or four days. This is a very big problem for Jake's brother, Tom. He can't be away from the Yeerk pool for that long. So Tom refuses to go -- but his father insists. Tom's Yeerk will do anything to survive. Including making his father less of a...

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. Jake knows that either choice is a major one, not something that a kid should be responsible for. But he's getting tired of the pressure. Even though he realizes his friends need him to...

Marco's mom is back. But she's not Visser One anymore. Marco's not even sure if she's still a Controller, but he's determined to find out. No matter what it takes. No matter what might happen. Marco wants his mom back. Jake and the other Animorphs realize that Marco is under some serious stress. And that the situation with his mom could very well jeopardize everything they've worked for. Now they also have to wonder if Marco will be the one to give...

Something is very wrong with Ax. He's sick, and the Animorphs don't know what to do about it. They can't take him to the hospital. They don't know how to contact the Andalite home world. And Ax is dying. Cassie and the other Animorphs come up with a plan. But it involves finding a new way into the Yeerk pool. There's just one problem: Jake, Rachel, Tobias, and Marco all come down with Ax's sickness. And now, for the first time, Cassie is on her...

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. Visser Three knows the "Andalite bandits" don't feed where he does, so there can only be one other place.Now the Animorphs have to figure out a way to stop a bogus logging operation. Because if Visser Three finds Ax in the...
