When Max and the Flock discover an unscrupulous scientist who is experimenting on humans in an effort to "improve" the human race, they decide that they must try to stop him, in spite of Angel's prediction about Fang dying.

"Ten years ago a girl with wings fought to save the world. Then she disappeared -- and now is just a fading legend, remembered only in stories. Hawk doesn't know her real name. She doesn't know who her family was, or where they went. The only thing she remembers is that she was told to wait on a specific street corner, at a specific time, until her parents came back for her. Someone is coming for her -- but it's not a rescue mission."--
