An eight-year old girl is the prime suspect in a series of bizarre, seemingly unrelated deaths.

Five teens who can "morph" into animals fight alien invaders. Elfangor warns the Animorphs about Yeerks.

Scared and curious, the Animorphs experiment with Elfangor’s gift. On Cassie’s family farm, Jake, Rachel, Marco, and Cassie take turns practicing 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,” or Yeerk slaves...!

There’s something suspicious about a new club called “The Sharing.” Jake’s all-star basketball player brother, Tom, has quit the team to join, and Marco’s father is also enthusiastic about signing up. When The Sharing holds a meeting at the school, the Animorphs, posing as Controllers, take advantage of the opportunity to find out more. They are led into an ominous “Yeerk Pool,” where Controllers must “revitalize” every three days to survive...but will the Animorphs ever get out alive?

Rachel’s best friend Melissa is acting strange and distant. Intent on finding out why, Rachel sneaks into Melissa’s house and morphs into her pet cat. In the process, Rachel is captured in cat morph. When Jake tries to rescue her in dog morph he is captured himself! Will the Animorphs escape before their two-hour time limit is up or will they become members of animal kingdom...forever?

Cassie's visions lead her to an injured Andalite.
