After going rogue from the Bureau of Supernatural Investigation, Kal Hakala is in Sin City battling an evil force from Nazi Germany.

After ten years on the force, Kal Hakala is free from the Bureau of Supernatural Investigation. All it took was faking his own death. Now he can finally focus on hunting down the monster that murdered his sister. With the help of trusted former teammates, he's on a quest to find an artifact that can activate a magical Tesla Coil, the only device powerful enough to kill a legend. But wherever Kal goes, trouble isn't far behind. And neither are his former employers at the BSI.

Kal's search leads him to Las Vegas, where he encounters the greatest peril ever to threaten our world—a peril currently residing in Sin City, but rooted in World War II Germany. Can Kal overcome an enemy so evil that annihilating millions is merely one phase of its master plan? The task seems impossible, but for Kal Hakala, doing the impossible merely requires patience and careful planning. The trouble is, Kal isn't exactly known for being patient and careful.
