A caustic fog blankets the Earth. Only the transparent barrier known as the Shield holds it at bay. It is the Amboians-an advanced alien species-and their technology that saved the last remnants of Humanity from the deadly Haze.
Cordelia Faucher, a scavenger known as the Haze Walker, has a secret she must keep hidden. Carter Gerro, one of the few Humans allowed among the City Guard is unexpectedly chosen to protect a member of the Amboian Council. A mercenary group known as the Amber Waves find themselves in over their heads after accepting a job they couldn't pass up.
As disturbing reports of attacks from beyond the perimeter of the Shield reach the capital city of Amboy, all eyes turn eastward.
It is these events that bring together the Haze Walker, a City Guardsman, and a band of mercenaries.
