Ted Dekker - Hacker

Seventeen year old Nyah Parks is a genius hacker whose world is unraveling. Deeply scarred from a horrific accident that killed her father and brother, and left her mother with irreparable brain damage, Nyah is barely holding the last shreds of her life together.

Now, her mother's health is deteriorating quickly and Nyah faces the grim prospect of losing her, too. One last ditch hope exists–an experimental brain surgery that could buy her mother more time. But Nyah must scrape together enough money to pay for it before it's too late.

Desperate and with no other choice, Nyah turns her programming skills to cracking the firewalls of the world's largest corporations. She exposes their weaknesses, and then offers her services to secure their systems from hackers.
