Books by Katherine Applegate
Attitude: Unobjectionable → Fairly Positive
Half-a-dozen youngsters witness the crash of a flying saucer and are given the power to take on the body of any animal they can touch by the Andalite pilot before he is killed by his arch enemy Visser Three of the alien Yeerks: slugs who take over other creatures' bodies.
Conventional young teenage pap. Some redeeming features based on the friendship between the children and the occasional heroism displayed by them, their allies, or on one occasion one of their enemies. Mostly though black-or- white goody-baddy stuff with sporadic moralising.
A group of friends, after indulging in some daft sorcery, find themselves trapped between two worlds, switching between them as they wake and sleep.
