The Silver Falcon

October 1990. A mysterious object is seen floating eastward over Alaska, resembling a silver falcon of Tlingit legend. Air Force radar can't see it. Fighter jets scramble to intercept the object, but all the pilots can do is watch it cruise across the border into Canada, where it comes down in a remote part of the Yukon Territory.
USAF special operator Jo Ann Geary, the White Vixen, is dispatched to Dawson City to assist Canadian Rangers in the search for the object in the Cloudy Range of Tombstone Territorial Park. They've barely started their hike when all radio comms with Ottawa and Washington go dead, but not before Jo is told about an unidentified aircraft dropping paratroopers north of the target's last known location. Who are they, and why do they want the Falcon?
As the weather deteriorates, Jo and the Canadian intelligence agent in command of the mission worry that the Rangers will be outnumbered and outgunned if they encounter the airborne troops, who are almost certainly Russians. At the White House, the president is told that the Falcon's technology, whether man-made or extra-terrestrial, could be so important that the invaders might possibly call in a nuclear strike from an offshore submarine if they're unable to keep the Falcon away from the allied force.
Thrust into the middle of indigenous Rangers who don't really trust her, unable to get help from Washington or Ottawa, and facing an enemy force that could be desperate enough to risk war, the Vixen must call on all her skills to survive and prevent the Falcon, whatever it is, from touching off a nuclear cataclysm.
