Warrior by Holly S. Roberts

The electromagnetic pulses were just the beginning. In their wake came the hellhounds; vicious, relentless creatures that tried to finish what the bombs started and tore through most of humanity.

Marinah lost everything when her father died. Once loyal to the Federation, she believed in their mission until their lies shattered her trust. Now branded a traitor and hunted as one of the monsters, Marinah is finally free to become who she was meant to be.
King, the ruthless leader of the Shadow Warriors, knows exactly what Marinah is and what she’s capable of. Together, they’ll take the fight to both the hellhounds and the corrupt Federation, striking from the shadows to give humanity one last shot at survival.

President Barnes rules the Federation with fear and control. He wants Marinah, King, and the entire Shadow Warrior resistance wiped from existence before they expose the truth he’s desperate to keep buried. And he’ll stop at nothing to silence them.
