About this book

Cassie and the Animorphs are on the run after the Yeerks repair a tiny alien ship that can sense morphing. If they morph, they’ll be found; if they sit still, the Yeerks may capture the blue morphing cube that started it all. With danger closing in, the team must keep the cube moving and outsmart Visser Three’s forces at every turn. Fast-paced action, tense close calls, and Cassie’s tough choices make this a gripping entry for sci‑fi fans.

Setting: contemporary suburban California; various urban and rural locations while evading the Yeerks
