Rowan of Rin is a children's fantasy novel by Australian author Emily Rodda.

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.

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.
