I think this book would be fine for ages 11 or 12 and up.
This book is about 6 kids: Max, Fang, Iggy, Nudge, Gasman (Gazzy), and Angel. They were all experiments (half bird, half human) and they escape. Now they are on the run and they have chosen Max as their leader. They think they have found somewhere safe to live until the creatures called the erasers kidnap Angel. Since Gazzy is only eight, they leave him behind. They also leave Iggy because he is blind. Max, Fang, and Nudge go to find Angel. On the way there Max sees a girl being bullied by some guys. She stops to help, while Nudge and Fang continue on. Max manages to save the girl, but gets shot in the shoulder (and wing) and can’t continue on. She goes to the house of the girl she saved. Her name is Ella, and Max tells them everything, even about her wings. They take her to the doctor for an X-ray. That is when she realizes she has a tracking device in her arm. She runs away and eventually finds Nudge, Fang and soon Iggy and Gazzy who also ran away. After finding Angel, they run to New York. That is when Max finds out she has a voice in her head, but she doesn’t know if it is there to help or hurt her. Then they find out that there is an underground experiment lab. They immediately go down there to see if they can find any research on their real parents. When they get down there, they find something that they never expected to find, something that could change their lives forever.
I loved this book. It was so good, and I think anyone between the ages of 11-15 would love it.
My favorite character would either be Fang or Iggy. Fang is very serious and to the point, while Iggy is funny and jokes around a lot.
This book has mild romance (one kiss), mild to medium bad language, and medium violence.
