The Sacrifice

Earth is still caught in the conflict between the Yeerks and the Animorphs, a group of kids who can turn into animals. The fighting has grown more intense, and the Animorphs now face a choice that could tear the group apart for good. Ax and his friends have worked out a plan to destroy the Yeerk pool, which would give humanity its best chance to reclaim the planet. The problem is that anyone else inside the pool would die too. With no time left to weigh the options, they must decide yes or no.
