Death's Good Dog - Aztec West

In 1521, while the Spanish were conquering the Aztec people, the Archangel Michael defeated their gods. Three hundred years later, the fierce, bloodthirsty gods of Ancient Mexico still sit dead on the shores of the Black Lake in the underworld, watched over by the only two gods the angels spared: Lord Death and his servant, the Black Dog Xolotl. When Xolotl accidentally resurrects the old gods and unleashes them on a world that's long forgotten them, he must return them to the underworld before Michael finds out, or he will be the next god sitting dead on the Black Lake.
It shouldn't be too difficult to wrangle them up though; newly reborn gods don't remember who they are, or that feeding on human blood will reawaken their powerful magic. But he might pay dearly for that underestimation when he matches wits with a god driven by a thirst for children's tears, and the certainty that Xolotl is a traitor against his own kind..
