Keira Vaughn, a maid who once cleaned up starship garbage for a noble, accidentally intercepted evidence of the parliament's silence, and has since been hunted to the edge of the galaxy. The exiled former law officer Wayne Wright quietly appeared and used the broken files as bait to guide her to tear apart the hypocritical order of the aristocracy. When etiquette officer Liv's secret report, defected engineer Toby's explosives and the whispers of the collapsed AI Zero are intertwined, a coup initiated by the bottom maid is rewriting the interstellar code with rusted machinery and burning memories.
