Iggy, Gasman, Max, Fang, Angel, and Nudge are altered humans that are kind of like bird people, they are on the run from horrible wolf people known as "Erasers" who want to take these "bird people" to a place they call "The school"
The Erasers found out where the flock was staying. They found Angel and took her back to "The School". Once the flock found out they had taken her, the kids flew a long hard way to get her back, but they did it, they rescued Angel.
After saveing angel from the Erasers, they flew home. On the way back they were talking, Angel said she read one of the Erasers minds and she found out they had files on all of them in New York City! After talking for a while they planed to go to New York City.
Everything was fine until all the sudden Max started have brain attacks. These brain attacks are making her see things, things like images to the institute in New York City, and she even hears a voice, the voice is leading them on where to go.
They listened to the voice that Max heard. The voice led them toa building in New York, They found their files along with alot of other people's. They decided to erase all of their files along with the rest of people's. The flock almost got caught and had to leave!
They escaped but while doing so they might have killed Ari, Max's brother. Most of the families were in Washington D.C. Max led the flock to the capital.
