Killing Heroes

Felicia Clifton is a decorated veteran from a family of cops and veterans. After a stint as an Army Ranger, she joins the DC police force. Her only goal in life is to rid the world of criminals. But after getting her partner killed, then shooting an unarmed youth, she is placed on desk duty.
When Felicia witnesses an attempted kidnapping, she comes face-to-face with the person responsible for killing special forces veterans across the US. The same killings that landed her father in jail. Felicia later wounds the killer, who seeks retribution by framing Felicia for murder.
Now on the run, Felicia must find the killer, clear her father, and stop a new terror, which threatens civilization itself. So terrifying that she joins the killer to stop it.
