Broken Reign

2025
In the wake of her first devastating case, Indie Reign follows new clues that suggest the same twisted beliefs are still claiming victims, testing how much more of herself she’s willing to break to stop them.
Series background & context
The Indie Reign series trades big‑city field offices for the shadowed hollows of Appalachia. Indie Reign returns to the rural county where she grew up, a place she left behind after her family was brutally killed and her grandmother vanished without explanation. Now, as a probationary K‑9 officer with the sheriff’s department, she’s determined to protect the community that failed to protect her.
In Twisted Reign, her first day on the job shatters any illusion that things have quieted down. A teenage girl is found hanging from a backyard swing. It could be suicide—except Indie’s instincts, honed by trauma and training, say otherwise. The death is only the latest in a disturbing string of “accidents” and suicides among local teens, and three of the dead left behind the same single, chilling word: Ascension.
With the help of her new four‑legged partner, a sharp‑nosed Belgian Malinois named Broc, Indie begins to see a pattern that points far beyond her small town. A hidden online community is targeting vulnerable kids, promising transformation or escape through death. Someone on the other side of the screen doesn’t think they’re killing children. They think they’re saving them.
Stone uses Indie’s “gift” with animals—an almost uncanny bond that lets her read Broc and other creatures better than most humans—to deepen the investigative work. Searches through woods, tense tracks in the dark, and scenes where the dog alerts to danger before any person senses it give the books a visceral, boots‑on‑the‑ground feel.
At the same time, Indie is wrestling with personal questions she’s avoided for years. Why was her family targeted? What really happened to her grandmother? And how much of the town’s current sickness is tied to the secrets adults have been keeping since she was a child? Every clue she uncovers in her official cases seems to tug on those older threads.
If you’re drawn to rural crime fiction where the land, the community, and the past are all part of the mystery—and you have a soft spot for hardworking K‑9 teams—Indie Reign’s stories offer a tense, emotionally charged ride.
