Twenty-four-year-old Ariadne Young is a quick-witted hacker living in a future America. Democracy has failed, and a new world order called the Enlightenment has risen. Their technology has produced the ultimate form of surveillance: the Node. A camera-like device implanted in the eye, it watches the citizens' every move, waiting to detonate-and kill-if the people disobey.

Desperate to avenge the long-ago deaths of her parents, Ariadne uses her hacking skills to uncover the truth behind their murderers. With the help of Amity, a sophisticated A.I. system, she remains hidden from the eyes of the government. But while deciphering a stolen code from an Enlightenment base, her mission is jeopardized when she encounters an Enlightenment agent. With her life on the line, she manages to escape with help from a rebellion group called Black Web, who provide her with the tools she needs for vengeance.

Ridding the world of the Enlightenment will grant Ariadne her greatest wish: retribution for her parents. But with the nation thriving and unified under the Enlightenment's plan, revealing the truth threatens to send society spiraling into chaos. Now, Ariadne must decide if her vendetta is worth upending society, returning it to certain anarchy and ruin.
