Summary

Scared and curious, the Animorphs experiment with Elfangor's gift. On Cassie's family farm, Jake, Rachel, Marco, Cassie, and Tobias practice their new morphing powers, experiencing, for the first time, what it feels like to be a horse, a cat, and a rat. The Animorphs, now confident about their new ability, return to the crash site to retrieve a lost disk given to them by Elfangor, who warned the kids to guard it with their lives. To their horror, when the Animorphs arrive at the construction site they find the place filled with "human-Controllers!"
