The Devoured and the Dead — Kristopher Rufty

Three families traveling through the mountains of North Carolina to claim their share of the gold rush become stranded deep in the forest, overwhelmed by the unrelenting snow and frigid temperatures. It doesn't take long for the food supply to run out, for desperation and harmful intentions to set in. When one of their own dies, they commit a depraved act to survive, a depraved act that unleashes a curse that will not stop until every one of them is either devoured...or dead!
