Operation Fury by Susan Hayes
She’s fighting for survival. He’s fighting for her soul.
Nyx was created to be the perfect killer, with death and violence encoded in her DNA. After years of tests, torments, and trials designed to push her to her breaking point, she’s survived by focusing on one thing –revenge.
Nova Force investigator Eric Erben lost someone he cared about. Now he’s on a mission to fulfill her last request – free her sister from the shadowy group holding her captive. Rescuing Nyx from her captors is the easy part. Saving her from herself will be a battle only love can win.
