City Without Stars [EPUB ebook] 

The only thing more dangerous than the cartels is the truth… In Ciudad Real, Mexico, a deadly war between rival cartels is erupting, and hundreds of female sweat-shop workers are being murdered. As his police superiors start shutting down his investigation, Fuentes suspects most of his colleagues are on the payroll of narco kingpin, El Santo. Meanwhile, despairing union activist, Pilar, decides to take social justice into her own hands. But if she wants to stop the killings, she's going to have to ignore all her instincts and accept the help of Fuentes. When the name of Mexico's saintly orphan rescuer, Padre Marcio, keeps resurfacing, Pilar and Fuentes begin to realise how deep the cover-up goes.
