In Ashen Verge, a city wired to kill, ex-cop Cal Rourke hunts the shadow behind his partner's murder. Five years ago, Eddie died chasing a signal—a hum that's claimed twenty-four lives and won't stop. From blood-soaked warehouses to a grid patched deep under the streets, Rourke tears through killers and ghosts—Graves, Shade, Tate—each a cog in a machine that's waited for him. Stitched up, bleeding out, and armed with a badge and a grudge, he'll end it or die trying. A relentless thriller of vengeance and silence, where every wire hums with death.
