Plot summary
One morning the people of Rin wake up to find that the stream that flows down from the mountain has slowed to a trickle. By nightfall, it dries up completely; the villagers are alarmed and distressed by this unprecedented crisis. The stream is essential for the survival of the bukshah, the herd of animals that plow the land and are rich sources of wool and milk, and hence also for the survival of the people of Rin. Because of the severity of the situation, six of the strongest, bravest villagers decide to climb the mountain - considered forbidden territory, with tales telling of a dragon living at its peak - in order to see what is wrong at the source of the stream. Strong Jonn of the Orchard, Bronden the furniture-maker, Marlie the weaver, Allun the baker, and Val and Ellis, the twin millers, volunteer to make the perilous journey. When it turns out that Rowan, the village weakling, has been given a map of the mountain that only reveals the path when he is holding it, the group reluctantly agree that Rowan must join them.
During the journey, the group must unravel riddles and persevere despite frightening situations to progress. One by one, each of the villagers breaks down and returns to the village when forced to confront their own greatest fears. Rowan, the most fearful of them all, proves to be the bravest after facing and overcoming each threat despite his fear. Having reached the dragon's lair at the top of the mountain, Rowan is able to remove a bone stuck in the dragon's throat, enabling it to breathe fire again and melt the ice in and around its lair. The melted ice rushes down a channel inside the mountain and becomes the stream that runs down to the village of Rin, carrying the remaining villagers back home with it.
