The Secret

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 woods, nothing will stop him from finding the Animorphs.
