The Underground by Katherine Applegate
Rachel discovers that oatmeal has a seriously weird effect on Yeerks. This is good news. The bad news is that they have to go back to the Yeerk pool to use it. The pool is more heavily guarded than ever. The Animorphs have been lucky before - but now their luck could be about to run out.| SKU | Unavailable |
