In less than a moment, unexplained intentions, then murder, upend life in Posadas County, New Mexico

Posadas County, sitting along New Mexico's southern border, has enjoyed a surge in visitors, jobs, and prosperity since rancher Miles Waddell used much of his inherited half billion to create an internationally renowned astronomy complex atop Torrance Mesa. Passion, not profit, drives Waddell. Yet benefits include a narrow gauge train linking the village of Posadas to NightZone. It's a boon to employees and for nature lovers, hikers, and birders as well as star gazers.

A ripple of unease is felt across the county with the arrival of developer—no, speculator—Kyle Thompson. Why did he and his wife quietly purchase a large scrubby acreage to the north of NightZone? Any light pollution would jeopardize Waddell's success. "Lights are like cancer cells. One comes, others follow."

Unease grows with a drive-by shoot-up at the Posadas Register, its 25 shots wounding a reporter and the paper's editor. Sheriff Bob Torrez and Undersheriff Estelle Reyes-Guzman see a connection to NightZone...and worse, a connection with Torrez's own nephew. Why?

And then murder strikes...
