A killer stalks the midnight streets of Mexico City. Is she a hardened vigilante bent on bloody justice? Or something far, far worse? On the violent barrio streets, Dulce Alvaro first showed a sadistic talent for murder at a tender age. It was a talent nourished by a ruthless crime cartel who honed young Dulce into a merciless assassin. 

Now, she is ROJA, a living weapon. An expert in the martial arts. A master of the machete. A genius with a machine pistol. But beneath all the discipline beats the heart of a deranged killer who deals death with savage glee. Roja's primary target is the only woman who can challenge her lethal prowess-the street avenger, La Muerta!
