Like everyone else in the Realm of Siir, a sixteen-year-old village lass named Allu knows that music is forbidden. It’s not that music doesn’t exist; rather, music is a power that the Masters in far-off Sifirithi hoard in order to dominate Siir and enforce their rule. But then Allu—musically gifted despite humble origins—finds herself conscripted to receive training and serve the Masters in Sifirithi. There, falling in love with Ned, a young instrument builder, Allu must either accept the powers granted her—or else make a dangerous decision to resist the Masters. Allu’s and Ned’s choices draw them into a perilous adventure in a fantasy world like no other.
