Night lasts for days on Jannix, and when the sun finally sets, no one can be sure they'll see another dawn. On a planet where darkness stretches for nearly a week, ex-detective Jack Tarelli lives with the ghosts of his past and the bottle that keeps them quiet. But when a billionaire's son is found murdered, Jack is called to his luxurious high-rise and pulled back into a world he's been trying to forget. What begins as a simple investigation twists into something far darker: a web of corruption, vengeance, and impossible choices. As Jack digs deeper, the boundaries between justice and obsession blur, and he realizes that some ghosts refuse to stay dead. A Knife in the Dark pulls readers into a shadow-drenched cyberpunk world of shifting loyalties and dying light, a sci-fi murder mystery that fuses crime thriller grit with science fiction noir atmosphere.
