Blackbird That Wasn't

What happens when Satan decides to invade Mexicos ancient deities? This takes place during World War II, so its savageness is hidden by the political war raging across the globe. Bruce Sherman and a small band of United States Marines are thrown into the clash with Satans evils. Not only are they fighting evils in Mexico but they are also contesting Mexico City, Washingtons indifference, and Aztec deities who refuses to fight the forces trying to dominate their domains. Bruces own men often refuse to believe what they are fighting.
