Mara Vale

Mara Vale is 16, brilliant, sarcastic, and perpetually one bad decision away from another meeting with someone carrying a clipboard. Schools call her disruptive. Counselors call her oppositional. Administrators call her a security problem. Mara would argue that their security being terrible isn't actually her fault. Online, she goes by NULLGIRL, a gifted hacker with an instinct for discovering hidden connections, forgotten systems, bad assumptions, and secrets people thought were safely buried. She's spent years learning that computers are easier to understand than people. Machines follow rules. People change the rules and then pretend they didn't. Getting Mara to talk isn't difficult.
