The Shadow Children Book 2: Among the Impostors by Margaret Haddix

This series by Margaret Peterson Haddix is about a futuristic totalitarian society where families are only allowed to have two children. If a third child is born, the Population Police come and kill it, even if the child has grown to adulthood. The series focuses on a third child named Luke who lives in hiding to survive. As he grows up in this confined state (and catches glimpses of other "shadow children"), he begins to develop the desire to live out in the open and help other third children do the same. Follow this daring boy/man as he makes friends and joins a secret, dangerous movement to bring about justice for all third children. This is a very intriguing series, which has made fans of several Rainbow employees! Each book is about 150-180 pgs, pb. ~Rachel
