According to the bio on Amazon: "Besides having taught college geography, Tierney is a former Solar System Ambassador for NASA's Jet Propulsion Lab. Exploring the Okavango Delta in Botswana and walking the Great Wall of China influenced the fiction she creates. Living among the Cherokee in her youth forced Tierney to see life differently as did raising a family in a mining/logging community in California and Missouri. "Life is an adventure! Embrace it," is her motto."
