Animorphs - The Invasion Series, Part 3: The Enemy Among Us

As if alien invasion isn't enough to deal with, Rachel finds out her divorced dad is moving 1,000 miles away and wants her to leave her friends, mother, and sister behind and join him in "The Stranger," the first of three 24-minute episodes based on the Scholastic book series by K.A. Applegate. While she is mulling over Dad's offer, Rachel and the rest of the band of morphing teenagers face a tempting offer: stay on earth and fight what appears to be a losing battle to the invading Yeerks, or take refuge on a safe planet with their families. In "The Leader," parts 1 and 2, Jake and Marco are caught morphing into animals and launched into space to face a powerful new Yeerk leader, Visser One, who turns out to be the mother Marco thought had been dead for two years. The three episodes from Nickelodeon's prime-time series are sandwiched by extra footage of Marco first making his case to quit the teens' quest to save the earth and then, after discovering his mother's fate, vowing to fight until she is free. This well-produced adventure series combines domestic tales with science fiction geared toward ages 6-12. --Kimberly Heinrichs
