The Sacrifice

the long version

The war between the Yeerks and the Animorphs is still raging. There are no more secrets but plenty of lies. 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 without destroying everyone else that may be there. And there's no more time to think about it. There's only yes or no.
