Calvin Rourke has worked Montana's backcountry for twenty-three years. He knows what abandoned vehicles look like, what missing hikers look like, and what the mountains can throw at a man. When a truck turns up on Service Road 12 with the keys still in the ignition and the owner nowhere to be found, he follows the trail into the pines — and finds something the mountains were never supposed to show him. A pit in the earth. A ring of scorched ground. Footprints that stop without explanation. And a federal response that arrives before anyone could have called it. Calvin Rourke will spend the rest of his life carrying what he saw that day. This is how it started.
