The Always War by Margaret Peterson Haddix

Tessa has never known a world without war.  For longer than she or her parents have been around, the country has been at war.  This has left the people depressed, poor, and struggling to survive.  Tessa is happy to hear that a childhood friend and neighbor, Gideon, is winning a medal for his military service because she hopes this will inspire her community and give them something to live for.

But Gideon isn't happy about his award at all.  He is filled with guilt about what he has done and determined to do something to make things right.

As Gideon, Tessa, and an orphan named Dek set out on one final mission, they begin to realize a shocking truth about this always war that has consumed everyone's lives for generations.

This is a quick read and interesting perspective on war and intelligence.  The Always War will make you think about war and truth in a different way.  As you read, look for place names that sound familiar but are a little off.  See if you can figure out the real places Dek, Gideon, and Tessa discuss and visit.  I recommend this for everyone, 6-8.  Enjoy!
