Every year, all 16-year-olds are tested for a contagious and deadly virus that can eliminate an entire civilization faster than the plague. Well, at least that's what they're told. The truth is they are testing for the presence of magic. If you are tested positive, you are assigned a color and symbol based on your ability. You can never see your family again and you can never go home. They train you for a war. A group of friends finds themselves at the camps, but when they escape, the camps have to find them and bring them back before they can create too many problems. They can't have the secret of the powers getting out. With constant curveballs and forks in the road, the kids must adjust and alter all their plans. With fights and sacrifices along the way, will their friendship last?
