Ember embraces her new persona, The Black Slaughter, and is ready to purge the small town of Whitsborough of its rotten core.

With Vin, Emmett, Travis, and Adri by her side, they will work together to flush out the malignant growths within their town's borders, even if it leaves a trail of blood in their wake. No one is safe, and nothing will come between Ember and her mission. Not even centuries-old secrets they unearth along the way.

As Ember ticks off each name on her list, she uncovers a dark picture painted by the wealthy and prestigious founding families, and at the top of the list is hers. Money talks, immorality is masked by power, and Ember finds herself caught in a world where her resilience is often tested. After being pushed too far, she succumbs to her inner villain, and no one is safe from her blade, no matter how much money they have.

Allies are masked enemies, and family becomes foe, and it's up to Ember to decide if redemption is possible.
