Light of Embers

From publisher blurb:

There is no road across the flats, but out there, beyond the desolation, is a line of dark-red light, viewable even this early into the gloom of sunset. That red line is rumored to be the shape of a road—a road from the Old World. The road lies in ruin, but something in the road now burns as a kind of ember, giving off a strange glow into the night sky... and it is rumored that somewhere, out far beyond the other end of that Ember Road, there lies a land that has not been utterly laid to waste. There are those who will do anything to find such a land.
