Animorphs

The battle is still raging, and it's out-and-out war. Jake and the other Animorphs have found a way to slow the Yeerks down, but now the Yeerks have decided the best way to win is to just destroy everything and everyone who gets in their way. Just when things look hopeless, Jake and the others discover help where they least expected: Taxxons. Creatures so foul and heartless, it's hard to believe that they're capable of having any feelings. But Jake and the others soon discover that the Taxxon resistance has its own problems with the Yeerks.

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 Animorphs. And no one knows who will win, lose, or live.
