Query: Rachel has an allergic reaction to the crocidle morph.

This book was about how Rachel got an allergic reaction to the crocidile morph and she couldn't control her morphing.She and Cassie got to go to this talk show because a Controller was gonna be there and talk about the benifits of the Sharing which is really a group formed by the Yeerks to get more human Controllers.So she and the other Animorphs go but because of her allergy to the crocidile morph and her un-comtrolled morphing, a disater happens! I suggest you read this book if you like the Animorhs!It's good.
