Las Vegas, Nevada. For some, a neon drenched playground. For Harmony Black, a graveyard of bad memories. But when your job is protecting humanity from the horrors of the occult underworld, you go where the mission sends you. 

The annual TechTopia conference draws Silicon Valley entrepreneurs, big thinkers, startup investors - and the Basilisk, a former German military intelligence officer turned freelance assassin. He’s in town to make a killing, and his target could be any of a thousand potential victims. To protect their source of information, direct action is off the table: Harmony and her team have to identify the target and stage a rescue without the Basilisk - or his mistress, the sadistic demoness Nadine - ever learning that they were involved.

Stranger things are brewing under the neon and glitz. The elite of the criminal underworld are flocking to the city like flies to a rotting corpse, rumors of a secret auction are swirling, and the assassin’s target has ties to Talon Worldwide - a corporation with a foothold on two parallel Earths. Soon enough, Harmony discovers there’s far more at stake than a single life. The consequences of this mission aren’t just global; they’re interdimensional.
