Gil, Max, and Pilgrim head to Aspen for a weekend of dog training with Pappy, a Marine Corps friend, and Max's son, Dan Dailey. But before they arrive, a blizzard sweeps the state, and a deadly terrorist assault descends on the ski town.

Pappy teams up with a ragtag group of survivors-a former biathlete, the last surviving cop, a savvy prepper, and a band of resilient youths-fighting to stay alive and uncover the terrorists' true motives. But as the chaos unfolds, they begin to suspect this isn't a simple attack. Could it be a distraction for something far more sinister?

Meanwhile, Sarah Gallagher and young Irmgard face their own dangers back home, stalked by a serial killer from the past. As a drone pilot uncovers the possibility of nuclear weapons and troops advance through the storm, Max, Pilgrim, and the K9s are pushed to their limits.

Packed with high-stakes action, intrigue, and a touch of faith, this is the battle of the century. Grab your coffee and settle in-you won't be able to put this thriller down.
