Cody Grant's mysteries take place in National Parks and feature Good Guys who love the parks and Bad Guys who love greed and corruption.
For instance, the Blackfoot park ranger in Yellowstone National Park is the only one who can figure out why the director of the National Park Service, who has never been known for "having green blood" (working for sunsets, loving the parks) is trying so hard to do good things for his park. And the mysterious way he rose through the ranks? Whitewolf suspects that Means will be president of the United States, and will not get there by being elected. Only his tribal customs can help him ferret out the devil in Grayson Means.
