Earth Sons

The End of the World came. Some say that what happened was inevitable due to humans’ treatment of Mother Earth; others, a fulfillment of prophesy. The descendants of the few survivors now live in a deadly world with black seas and poisonous air; contaminated food and water. Genetically enhanced beings now own the planet. The era of Humanity… is over.
Yet there is hope: It is named Blue, for its color. A chemical that can purify the most contaminated water, make any food edible, and even cleanse the air when applied to the inside of a mask. Blue cannot be duplicated, however. No one knows where it was made or how it seemed to be everywhere at once, in a world with little communication or means.
Now the supply is running out… and the hunt begins.
