Where she lived, there was one law: either you’re with us, or you’re against us—which meant: either you’re alive, or you’re dead. Wars between drug cartels, fights over drug trafficking, brief alliances of rival mafia clans that soon turned into bloody, merciless showdowns—this was the world she lived in. A world where even in folk ballads they sing that “going against the law is our family tradition.” Teresa Mendoza chose to stay alive. So, stepping over heads (and forcing herself to forget what tears are), acting hard and without mercy, she became the godmother of the drug mafia in southern Spain—the Queen of the South, as people called her. The novel was adapted for film twice.
