Abstract
On the slopes of a vertical land where people’s lives are bounded by how high and low they are able walk on the single path that connects their world, the young widow Len Rope-Maker watches as years go by and her son Cam never finds his limits. Long past the time when other youths in Home Village have found their boundaries, Cam keeps climbing higher and lower, pushing on with his sweetheart Fox who also shows signs of being a Far-Walker. But Cam’s drive to venture far nudges him towards the top of the world, while Fox’s sends her downward, toward the mythical sea at the bottom of all things. Both are true to their own heart’s calling.
