A grieving 17-year-old unsumming teenager discovers his voice carries a root frequency that completes a five-clan chord capable of shattering the glass dome sealing a city. 

SYNOPSIS:

One hundred and fifty years ago the industrial systems of the old world began poisoning the soil and the air. They knew. They continued. The contamination built across generations until the choice was clear: remediate — which would cost everything — or enclose — which would cost everyone else. The city of Vron chose enclosure. Eighty years ago the first dome went up. The founding document was honest: the people outside are not our responsibility. Four administrators have held the dome. The current Commander — the fourth — has ruled for thirty years. He did not build the system. He inherited it and decided it was right. Outside the glass: five clans surviving in poisoned wasteland across generations.
