Sixteen-year-old Ruby Daly never thought she could survive the terrible plague that killed 98% of American children. Instead, it has succeeded and like all those who survived it has unnatural powers. They are described using a color: the greens are super intelligent, the blues have telekinesis, the yellows control the electricity, the oranges have power over the minds of others and the reds dominate the fire. Ruby is an orange and as such is dangerous. He is sent to Thurmond in a field of his kind, from where he fears for the future flees. From that moment, his existence will change forever.
