Ruby Rose was supposed to be fighting Grimm in the forests of Remnant. Instead, a blinding flash of silver light drops her into the rain-slicked streets of near-future Chicago-a world where there are no monsters, only the cold, calculated greed of the ctOS network. Disoriented and alone, Ruby crosses paths with Aiden Pearce, the "Vigilante" driven by a ghost from his past and a hunger for vengeance. He's a man who fights with code and shadows; she's a girl who fights with a giant scythe and a heart full of hope. It's an alliance born of necessity, but as Ruby's superhuman speed begins to glitch the city's surveillance state, she becomes the most wanted "anomaly" in Blume Corporation history. Together, the Hacker and the Huntress must navigate a web of underground gangs and corporate conspiracies. Aiden is looking for the men who killed his niece-Ruby is just looking for a way home. But in a city where every camera is an eye and every phone is a weapon, Ruby's idealism might be the only thing capable of pulling Aiden back from the brink of darkness. Red petals meet the Windy City. The system is about to be breached.
