About Death in the Valley

In the hottest place on earth, every breath could be your last.

When the body of a young woman is found on The Racetrack—one of Death Valley’s most isolated and unforgiving locations—Special Agent Emme Helliwell is called to investigate. With her division facing devastating budget cuts, failure isn't an option—and neither is letting her personal life interfere with the case.

At first, the case looks simple: a deadbeat boyfriend, a successful girlfriend, a brutal end. But as Emme digs deeper, the facts refuse to fit. Instead, she uncovers a deadly web of drug traffickers, corporate corruption, and a plot that reaches far beyond a single murder.

Now Emme must navigate blistering desert heat, ruthless enemies, and impossible choices as she races to stop a conspiracy capable of inflicting catastrophic damage on the very parks she’s sworn to protect. 

Perfect for fans of C. J. Box, Nevada Barr, Paul Doiron, and Jane Harper, this fast-paced National Park thriller combines a gripping murder investigation with unforgettable wilderness, relentless suspense, and high-stakes action.
