Morphing is certainly more fun than Sega -- you can soar as
an eagle and walk as a cat. But being an ANIMORPH is by
no means just fun and games. Rachel knew better than
anyone. One of her best friends, Melissa, is acting very
strange. And it looks like Melissa's dad, who is also the
school's Assistant Principal, may be connected to evil aliens.
Rachel can't tell Melissa what the ANIMORPHS have
learned, but Melissa doesn't seem interested in talking to
Rachel these days anyway. Could Melissa be one of "them?"

With the help of Jake, Cassie, Tobias and Marco, Rachel
plans to enter her friend's house as a cat, intent on unlocking
the secrets from within. If only Rachel could keep her mind off
mice...
