The Last Emperox: John Scalzi

The Last Emperox is the explosive conclusion to John Scalzi's Interdependency series.
Can they escape the end of an empire?
Entire star systems, and billions of people, are about to be stranded. The pathways that link the stars are collapsing faster than anyone expected, accelerating the fall of civilization. But though the evidence is insurmountable, many are in denial. And some even attempt to profit from the final days of this golden age.
Emperox Grayland II has wrested control of the empire from her enemies. But even as she works to save her people, others seek power. And they will make a final, desperate push to topple her from her throne. Grayland and her depleted allies must use every tool at their disposal to save themselves and humanity - yet it still may not be enough.
Will Grayland become the saviour of her civilization... or the last emperox to wear the crown?
