They just wanted a road trip. Sarah Constantini and Jennifer Monroe load up their lifted 2019 Jeep Wrangler Rubicon and point it west, chasing off-road trails across America with no plan except adventure. Then they find the first body. What starts as a detour in the Georgia mountains becomes a multi-state hunt when a calculating serial killer begins staging victims along remote trail systems. He knows terrain. He knows how to disappear. And when Sarah disrupts his pattern, he decides she isn’t just a bystander— She’s the opponent. From the Ozarks to the red rock cliffs of Moab, the chase turns personal. The killer studies them. Tests them. Sabotages the trails beneath their tires. Law enforcement gets pulled in. Federal agents clash. And somewhere between switchbacks and sheer drop-offs, survival becomes a matter of inches. But he makes one critical mistake. He assumes they’ll panic. He assumes they’ll fracture. He assumes wrong. Fast, sharp, and relentless, Mud, Blood & Axles is a high-octane thriller where the road is deadly, the cliffs are unforgiving, and two smart-mouthed women refuse to be hunted. Buckle up.
