Yellowstone Standoff takes readers deep into the backcountry of a wildly popular national park. When Yellowstone National Park's grizzly bears and gray wolves suddenly and inexplicably go rogue, archaeologist Chuck Bender teams with his old friend, Yellowstone Chief Ranger Lex Hancock, to defend the suspect members of a group scientific expedition. Soon, Chuck finds himself defending the lives of his family as an unforeseen danger threatens in the storied national park's remote wilderness.

SCOTT GRAHAM is the author of the acclaimed National Park Mystery series, featuring archaeologist Chuck Bender and Chuck's spouse Janelle Ortega. In addition to the National Park Mystery series, Scott is the author of five nonfiction books, including Extreme Kids, winner of the National Outdoor Book Award. Like most visitors to America's first national park, Graham was awestruck by Yellowstone as a child. His fascination with the park has continued in the years since, with numerous visits to Yellowstone's geyser- and wildlife-filled front country and its incomparable wilderness. Graham is an avid outdoorsman and amateur archaeologist who enjoys mountaineering, skiing, hunting, rock climbing, and whitewater rafting with his wife, who is an emergency physician, and their two sons. He lives in Durango, Colorado.
