"Let the wicked flee the approaching darkness. Those who continue to practice injustice will receive no mercy."

The words of Lumen resonate through the billowing mists of darkness that enshroud those who perpetrate evil. All who mock justice and destroy the lost will eventually face a reckoning. For some, the reckoning will be prison. For others, the warnings of the mysterious presence in the dark will go unheeded. Their judgment will be in eternity.

Detective Thornbush of the Caliginos City Police Department tracks down a serial killer with a startling trademark. His victims are bloodless, with two marks on their necks, similar in shape, size, and distance to two canine teeth from a human mouth. He is aided by a school counselor, a local pastor, and a mysterious doppelganger. The pastor is anxious to restore a runaway daughter to her mother before she becomes the next victim. The school counselor is surprisingly detached considering he had close associations with most of the victims. Who is the doppelganger and how will he use his powers to cloak himself in an inky blackness, a darkness that can be felt?

Justice, mercy, and redemption will be explored in this superhero-suspense story about adults and teens living according to their own mores in a world of darkness.
