Burn It All Down by Amber Lynn Natusch

VICTORY IS SWEET━VENGEANCE IS SWEETER.
After three failed attempts on Kylene’s life, it looks like the Advocatus Diaboli might finally be done hunting her.

Or not.
Sure, our girl’s had a couple weeks reprieve from near-death experiences to deal with the lost dream of freeing her father from prison, but when mob witnesses with potential information that could break her dad’s case wide open again start dropping like flies, Kylene and Agent Dawson find themselves right back in the thick of things—and all the danger that entails.
Only this time, they won’t escape its grasp.

BURN IT ALL DOWN, the fourth and final YA mystery novel in the Hometown Antihero series by Amber Lynn Natusch.
