A massive solar flare erased nearly all color from the surface of the Earth, and the mutated descendants of the human race exist in a state of slow decline. What little color remains now holds a strange and seductive power. Some people, like the lone-wolf professor Avidia, try and understand it. Others, including the cult-like Iodopsy Order, use it for power and control. When an Order assassin draws innocent bystanders into their rivalry, it’ll take everything Avidia has to save their lives…and his own!

A cosmic disaster erased almost all color from the world, and now the mutated descendants of humanity live in a moody, noir cityscape draped with shades of grey.

Standing against them is Avidia, a gun-toting investigator and scientist who works outside the law. If he's to prevail, he'll need more power--which means surviving an incredibly dangerous new experiment, even as the Order moves ahead with the consummation of all their schemes!
