Empowered: Agent (The Empowered Series Book 1) by Dale Ivan Smith

The world says those possessing superpowers are either heroes or villains. But what if you’re both? Mathilda Brandt isn’t the angry, out-of-control teenager she was before she got out of jail. She’s hungry for a chance at a normal life, but when a gang threatens her sisters, she has no choice but to use her illegal superpower to protect them. A secretive government agency gives her a choice: go back to prison for life, or infiltrate a notorious super-villain group in order to stop a psychotic Empowered. To save her city, her family, and herself, Mat must become the last thing she ever wanted to be again: a criminal.
