Great series. Engineered drug to increase addiction and keep its users alive longer has created a zombieapocalypse. A group of special ops mercenaries are deployed without knowing what has begun. Their mission? Get the cartel butcher that has been committing horrible attrociites. The part that stinks? A commander who is corrupt and the fact that they have to leave the cartel leaders replacement in charge of the facility. Mariachi bands, pinatats, zombies and more. Great way to kick off the zombie apocalypse. I was voluntarily provided this free review copy audiobook by the author, narrator or publisher
