Lily knows she can take care of herself – but can she bring hope to a dying world?

The earth has sickened.

Centuries of war and greed have transformed a once resource-rich planet into vast graveyards, dotted by settlements of stubborn survivors who are forced to horde electricity and clean water.

Survivors who refuse to give up.

And some, like her deaf brother Gabriel, hold fast to a final dream. Gabriel wants to hear the Silversong. Just once, to hear music of the gods.

Guided by her unpredictable companions and the kami she keeps in jars, Lily sets off with the last battery on a desperate quest to find the Silversong in the hope that, even if it isn’t able to save the dying planet, it will at least bring a smile to her brother’s face.
