Cyberblade

Under Neo Mars, each citizen is assigned a floor underground, and the deeper you live, the nearer you are to the underworld. Lex arrived here as a small child fleeing a war, and so many years in the dim tunnels have blurred her memories of the sky. On the day of her final exam, her future is undecided: she will either rise from the Second Floor or be sent into the gang-controlled shadows to labor until death.

A priest of Zeus and a nobleman of high birth will decide her fate. The examination, however, turns out to have been a deception. Equality is granted only to a select few, and because Lex is an outsider, her bloodline shuts her out of happiness. Rules, she concludes, bind only those who obey them. If the world refuses to serve her and her people, the machinery of the enginestate must be smashed and something new built in its place.

Government enforcers, a deranged cyborg, a family secret and an ancient power all stand in her way. If she falls short, and a single girl cannot tip the balance of humanity alone, she plans to drag the corrupt down with her into Hades, where they can burn together. Her reasoning is that equality forged in fire is better than misery for the masses.
