We let Among the Enemy and Among the Betrayed go because they just weren't as good as Among The Hidden.

FROM AMAZON: What does it mean to save yourself?

Nina Idi - a third child in a society where families are allowed only two children - has been betrayed by the boy she loved and arrested by the Population Police for exposing other alleged third children. Angry and confused, Nina knows only one thing for sure: She is innocent of the charges. But now she is faced with the most difficult choice of her life: Get three other prisoners to admit they are shadow children and be spared herself, or refuse to cooperate and be killed. The options are clear. The choice, Nina discovers, is not....

"Everything that had happened to Nina was real. She had real handcuffs on her wrists, real scars on her back, real fear flooding her mind.
"'They're going to kill me,' Nina whispered, and it was almost a relief to finally, finally give up hope."
In a society that allows no more than two children per family under penalty of death, third children are forced into hiding, or to live with false identity papers. In Among the Impostors, Nina Idi was arrested for treason for supposedly trying to trick the Population Police into arresting other students she said were illegal third children. Now she faces torture or death -- unless she agrees to betray three other imprisoned third children. Her dilemma intensifies when she meets the prisoners -- who are only ten, nine, and six.
As she did so brilliantly in the Publishers Weekly best-selling Among the Hidden and in Among the Impostors, Margaret Peterson Haddix once again brings readers to a world in which nothing is as it seems -- a world in which an imprisonment leads to an adventure of mind, body, and spirit. ( )

My memory tells me this was my favorite book from the entire Shadow Children series when I read it years ago, but that's pretty much everything I can still remember about it. I definitely have to reread the books in order to refresh my memories. ( )

I try to express only my most honest opinion in a spoiler-free way. Unfortunately, there is still always a risk of slight spoilers despite my best efforts. If you feel something in my review is a spoiler please let me know. Thank you.

This book told the story from a different person's point of view, but still a shadow child. I liked the switch up, and the ending was amazing. These are short and easy to read books with a scary kind of plot. I'm excited to see how it progresses. ( )
