Animorphs 22 - The Solution

David, the newest Animorph, is not what he appears. His need to control the other Animorphs and Ax 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.

Animorphs 23 - The Pretender

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, the other Animorphs, and Ax decide to do a little checking on this "cousin." And what they discover will change the rest of Tobias's life...

Animorphs 24 - The Suspicion

Cassie, the other Animorphs, and Ax 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 and Ax have a new dilemma. Because the Helmacrons have their own secret weapon: They can shrink other beings down to their size. And, if they don't get their ship back soon, everyone on the planet is in for a little surprise...

Animorphs 25 - The Extreme

Marco, the other Animorphs, and Ax have managed to find out where the Yeerks are planning to build their next ground-based Kandrona. That's a good thing. The location is supposed to be somewhere near the North Pole. That's a bad thing. The Animorphs and Ax know that the Yeerks are a "cold-blooded" species, but this is a little nuts! Who wants to be near the North Pole without Arctic morphs -- and wearing spandex?
Even so, the kids know that if the Yeerks succeed with their plan, Earth is pretty much done for. And Marco, the other Animorphs, and Ax aren't quite ready to give up the fight...
