The Graves Crew and the Road of Doom — Kenneth McDonald

The Graves Crew has split up. Without their leader, the men of the crew face what might be their toughest challenge yet: building a road up an almost sheer mountain. The job is hard enough, but something else waits for them atop the mountain, something that doesn't want the road to make it through. Meanwhile Graves, alone with Keev in the Duke's capital of Kalvanis, finds that danger also lurks in the heart of the White Order's power, a hidden enemy that wants to use him to advance its own agenda.

This is the fourth story in the “Graves Crew” series.
