Thurava of Astrava is intended to become a herder, a most honored position for her dwindling community that clings to life on the banks of the Najimov, the river that's the lifeblood of the high desert. But the Glass City on the horizon threatens the delicate balance the Astravans have managed to hold on to for centuries, polluting the air and water as the city grows bigger and bigger. The Glass City's clockwork liaisons offer to bring the Astravans into the Glass City's walls, but they will have to give up their ways and their precious herds to do so. Thurava must decide who she is without her animals, using the stars as her guide, putting herself on a collision course with the secrets the Glass City holds dear.
