City Without Stars

Set in Mexico, among the worst of the worst behaviour of the cartels, and to be frank, men, a union activist makes a stand. Tim Baker has created wonderful characters in Pilar and Fuentes.

From the Blurb:

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.
