St. Mercy by John Zurr Platten

From the writer of Jurassic World Evolution, The Chronicles of Riddick: Assault on Dark Athena, and Wanted: Weapons of Fate comes a revenge tale that spans millennia! No good deed goes unpunished.

When Mercedes Oro, a young missionary on the outskirts of a small frontier town, takes in and cares for a dying outlaw, the outlaw’s gang repays her by attacking her mission, killing her family, stealing the golden artifacts she swore to protect, and leaving her for dead with a dagger through her heart. Unbeknownst to the gang, the cursed dagger resurrects Mercedes, and she is reborn as St. Mercy, an avenging angel of death. Now, she’s out to recover her gold and deal violent retribution to those who wronged her, all while confronting Toctollissica, the spirit in the cursed Incan artifact that’s keeping her amongst the living.
