Overture is the capital of an empire that has built its entire civilization on magic — wealth, status, and daily life all flow through it. Now rumors of revolution are spreading through the city, and a rogue faction is pushing for the kind of equality the ruling class has no interest in granting. An Octave Higher follows three people from entirely different walks of life — Elise, Franz, and Frederic — who are brought together by a single broken piano. In Overture, healing magic cannot be used on inanimate objects. Elise intends to do it anyway.
