"Jake, Rachel, Macro, Cassie and Tobias were just kids until they were given the power to morph. Now they're the only ones who can save the human race from the evil Yeerks. But can Tobias still help now he's a hawk? Or should he just forget that he was ever a boy, and fly away for ever"--FantasticFiction.com.
