To tell a story set in the Sonoran Desert, which occurs in only one region of the world, we must include the iconic species of plants and animals who are its defining features. Their presence maintains the balance of life and contributes to the great beauty of this desert landscape. The saguaro cactus is its signature plant life, who some believe evolved from a tree in the tropical rainforest that dried to a savannah and then to a desert over thousands of years.

Threshold tells the stories of many desert plants, trees, insects, invertebrates, and mammals. One strategy for conserving water is to be active at dusk and dawn. These animals are said to be crepuscular (as contrasted with nocturnal). The jaguar is thus, and also nocturnal. Panthera onca is the third largest of the cat family with a bite more powerful than the tiger or lion.
I named the jaguar character in Threshold. Duma. With the risk of personifying a wild animal by human standards, I tried to stay strictly to the known biology, behavior, and observed lifeways of jaguars in the Sonoran Desert. In my story Duma obtains his name from first graders in Phoenix. You’ll have to read the book to learn how that came about. Below you see another feature of this remarkable character: he is an albino, a White Cat, causing local observers to refer to him as the “ghost cat” as he moves about the fields and pastures of farms and ranches, terrifying livestock and infuriating their caretakers.
Duma is my writer’s device to represent wild nature and the impact of a changing climate and human activity on his lifeways. His story also allowed me to describe the labyrinth of environmental and conservation laws on both sides of the border and how Duma becomes, literally, emmeshed in them. He crosses the U.S. -Mexico border while roaming his natural range which stretches from Sonora in Mexico north to Phoenix in Arizona. Duma is caught up in the social and political turmoil.
It is important to me to consider the lives of other species who share our habitats in what is a human centric world.
