A wizard, a werewolf, and a watchmaker walk into a bar...and don't come out alive.

Two months after the infamous Etruscan Incident, it's back to normal for DSI—as normal as life can be when you hunt monsters on a salary. The rest of Nick Riker's elite team has finally returned from France. Cooper Lee has healed from his nightmare trip to the Eververse. The remnants of the battles with Charun and Tuchulcha have been swept under the rug. And the exploding boathouse in Holden Park has (almost) been rebuilt.

All is calm in Aurora, Michigan.

Until a grisly triple murder in one of the city's most popular bars destroys the delicate balance between three powerful forces. A werewolf, a wizard, and a former mayor turned watchmaker wind up in body bags, and their deaths pit the ICM, DSI, and Aurora's Wolf community against each other in a blame game of epic proportions. And as the accusations spiral out of control, threatening a supernatural war on Aurora's streets, it's up to Riker's team to keep the peace before blood stains the sidewalks.

Meanwhile, Cal is struggling to overcome the consequences of his trip to the Etruscan Underworld. Haunted by visions of the future in the form of disorienting déjà vu, he's terrified he'll fail his team at crucial moments. But with the threat of violent riots hanging in the air, Cal has no choice but to power through and pray for the best.

Because one misstep on this case could mean the downfall of the city he loves.
