Kill Process (Kill Chain)

By day, Angie, a twenty-year veteran of the tech industry, is a data analyst at Tomo, the world's largest social networking company; by night, she exploits her database access to profile domestic abusers and kill the worst of them. She can't change her own traumatic past, but she can save other women.
 When Tomo introduces a deceptive new product that preys on users' fears to drive up its own revenue, Angie sees Tomo for what it really is--another evil abuser. Using her coding and hacking expertise, she decides to destroy Tomo by building a new social network that is completely distributed, compartmentalized, and unstoppable. If she succeeds, it will be the end of all centralized power in the Internet.
 But how can an anti-social, one-armed programmer with too many dark secrets succeed when the world's largest tech company is out to crush her and a no-name government black ops agency sets a psychopath to look into her growing digital footprint?
