"Chester has been traveling from village to village, searching for his kidnapped father. One night while fiddling to earn a few coins, he accidentally connects to the Song, the music that fuels every aspect of the world. It's illegal to interact with the Song - only a licensed Songshaper may bend music to his will - and when Chester is caught, he's sentenced to death. But just before the axe is about to fall, someone in the crowd - a member of the infamous Nightfall gang stages a daring rescue, whisking Chester into the Hush, a shadowy nightmare mirror-world where Music can be deadly and Echoes can kill." -- From the flyleaf.
