Tiger Fight [EPUB ebook] 
Mexico’s drug lords and old gods

When a gringo ex-pat foolishly steps in to defend an Indian woman from an obsessed drug trafficker, he finds a still living world of ancient myths. With the drug traffickers henchmen on their trail, they flee to her village in the mountains where an old tradition is about to be celebrated with ritual combat. When the protection of villagers and friends isnt enough, violence saves their lives, fulfilling the ancient myths, and preserving the old ways of the village.
