About this book

Strange activity in the woods behind Cassie’s house hints at a dangerous Yeerk plan, and the Animorphs realize their secret refuge—and Ax’s survival—may be at risk. Cassie leads the team on a mission to uncover a bogus logging operation and protect the wildlife she loves, all while keeping their identities hidden. Fast-paced action, clever animal morphs, and tight teamwork drive this installment. Great for middle-grade readers who enjoy sci-fi adventure, animal facts, and high-stakes undercover missions.

Setting: suburban woods near Cassie’s farm, contemporary small-town America
