Although Nim and Aria have known each other all their lives, they are constantly at loggerheads with each other. Nim is a serious, young boy whose principal interest is to become a top aviator, flying the prestigious hot air balloons that fly between the rocky spires of their world. Aria, on the the hand, is a fun-loving girl who lives for music and dance, and whose prize possession is the most famous musical instrument of the spire community - the unique redrim flute. No other flute is like it in tone or beauty, and there are some who connect it with magical powers. Neither Nim nor Aria could possibly have predicted the strange sequence of events that would cause them to become stranded in the dangerous forests that surround their rocky home, and where they would be utterly helpless against the sinister Shadowfolk that live there. Nor could they have appeciated how crucial the redrim flute would be to their own survival, as well as to the survival of their whole community. The Redrim Flute is an adventure story that will appeal to all the family. It is a story of suspense, danger and excitement. It is also a story of how friendship and loyalty can surmount the most terrifying of obstacles. However, there is more to the redrim flute than might first meet the eye. Although the story is set in a fictional land of rocky spires and dense forests, there are serious messages regarding our own world in terms of global economy, environment and the relationships between different peoples.
