Colorless 4.

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. There is great power hidden in what little color remains, and a secretive cult known as the Order hopes to use that power to awaken their mysterious gods. 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!
