Beyond the Last Mark is a tale of hard men on hard ground, pushing past the edge of maps and memory. When two seasoned frontiersmen set their sights on land no one claims and few return from, they discover that the wilderness keeps its own reckonings. Hunger, weather, and unseen enemies test not only their skill, but their trust in one another. Out where trails vanish and promises mean little, survival comes at a cost—and some lines, once crossed, can never be stepped back over.
