A routine flight over the Canadian Rockies ends in disaster when Northstar Flight 212 crashes deep within the wilderness during a brutal winter storm. With rescue nowhere in sight, a group of strangers must learn to survive freezing temperatures, dwindling supplies, injuries, and the unforgiving reality of isolation. Among them are Y/N, a capable survivor determined to keep everyone moving forward, her chaotic best friend Tatum, and Orion Dean Sullivan—a wilderness search-and-rescue guide who seems to challenge her at every turn. As days become weeks and weeks become months, survival stops being their only concern. Because the wilderness has a way of stripping people down to who they truly are. Friendships form. Trust is earned. Hearts become tangled. And the people who walked onto the plane are not the same people who emerge from the wreckage. If they emerge at all.
