Query: Fabulous Book

The book is one of the best books I've read,and the best book I've read of the animorphs series.I like how there is a yeerk in her head and she has to keep the animorphs a secret,Cassie morphs a butterfly,a monarch butter fly to be exact.I have already read the book so I dont want to give it away.But you really really should read the Visser number 23.Tobias morphs to ------ -,I did that not to give away what Tobias morphs. My favorite part is at the end of number 19.That is all,Bye. But before I go let me tell you about the Animorphs Tv series.Its about the books.
