Snake-Eater by T. Kingfisher

Perfect for fans of Silvia Moreno-Garcia, Chuck Tingle, and Rachel Harrison.

With only a few dollars to her name and her beloved dog Copper by her side, Selena flees her past in the city to claim her late aunt’s house in the desert town of Quartz Creek.

Selena loves the strange beauty of the desert. But the people of Quartz Creek share their town with others, old gods and spirits whose claim to the land long predates their human neighbors. When Selena’s search for answers leads her to her late aunt’s journal, she discovers a sinister truth about her new home: it’s the ground of an ancient god known simply as “Snake-Eater”, to whom it seems Aunt Amelia owed a debt.

Snake-Eater has taken a sinister liking to Selena. And now that she’s the owner of his home, he’s hell-bent on collecting everything he was promised.
