Drug cartel wars, the struggle for drug trafficking, short-lived alliances of warring mafia clans, soon turning into bloody, ruthless showdowns - this is the world in which she lived. A world where even in folk ballads it is sung that “going against the law is our family tradition.” Teresa Mendoza chose to stay alive, therefore, walking over heads (and forcing herself to forget what tears are), acting tough and merciless, she became godmother the mother of the drug mafia in the Spanish south - the Queen of the South, as she was popularly called. The novel was filmed twice.
