Edge of Justice

Publisher's blurb:

The wasteland of what was once New York is a land where chaos reigns supreme and the law of survival is etched in the bones of the fallen. From the ashes of the old world rises a silent order, one that few know and fewer still understand. A clan of assassins, bound by a secretive code, moves through the desolate remains of civilization, restoring a balance known only to them. They are the Veiled Blades, ghostly figures who strike without warning, disappearing into the darkness before their enemies can scream. Justice in this world is not decided by courts, but by the sharp edge of a blade hidden in the night.
