In the ninth book in Graham’s National Park Mystery Series, an archeologist must stop a century-old crime to save his daughter.
"Death Valley Duel is a taut, smart, and propulsive thriller that will keep you spellbound. Scott Graham has written a love letter to the California desert, and to parenthood, and to the athletes who push themselves past limits most of us cannot even imagine. This novel is a steady, dangerous, and addictive race toward justice."
