Viva-3 was built to discover secrets. But they made her too well. She's the perfect spy: the lethality and persistence of the police clockworks in a body that can pass as human. What the Empire's police don't know is that she doesn't have to obey their orders or her programming. She can think and decide for herself. And she's doomed if they find out. Viva is sent undercover with orders to unmask the city's vigilante hero, Penny Dreadful. She is supposed to stop his one-man war against the criminals of Monte-Ostrum. It will be dangerous, but just maybe Dreadful will be more useful as an ally rather than an enemy...
