Back again with in this case a trilogy you probably haven't read that you should. The Chanters of Tremaris trilogy by Kate Constable is set in a world where magic is controlled by different songs. Each land is known by the different songs, and magics it produces. Calwyn has lived in the secluded home of the ice priestesses her entire life and has known nothing of the world outside until a mysterious injured visitor comes and bring the serenity (and boredom) of her existence crashing down. Over the course of the trilogy, Calwyn is exposed to a larger world then she ever imagined and she is in the center of changing it all.
This book is great for anyone who loves epic fantasies with a hint of romance.
