Bonneville Betrayal. A Cali Rhodes Cozy Travel Mystery (en Inglés) - Alexis Childers

When nomadic mechanic Cali Rhodes detects a strange anomaly on the sweltering Bonneville Salt Flats, she digs down expecting to find a melting reactor core. Instead, she breaches Project D.E.E.P.-a subterranean, luxury doomsday bunker for the ultra-rich. Hired on the spot to fix a failing five-ton air scrubber, Cali plans to do the heavy lifting, collect her hazard pay, and get back to the open road in her trusty van, The Wanderer.

But her timing couldn't be worse.

The bunker's automated "Spring Readiness Drill" initiates, dropping the ten-ton blast doors and sealing Cali underground with the elite residents for a mandatory week of isolation. The simulation quickly turns deadly when Arthur Pendelton, the community's tyrannical rule-enforcer, is found dead in the bunker's airtight Seed Vault.

With no way in or out, and the paranoid preppers ready to turn on one another, Cali must team up with the bunker's exhausted Chief Engineer to catch a killer. But Cali isn't your average sleuth; she doesn't rely on town gossip. She tracks fluid dynamics, mechanical tolerances, and pressure drops. In a closed-loop system, every killer leaves a mechanical footprint-and Cali is determined to find it before the murderer turns the bunker's life-support systems against her.

Bonneville Betrayal is a gripping locked-room mystery where high-stakes suspense meets blue-collar brilliance.
