Coyote Songs, the latest novel from Gabino Iglesias, covers a bold stylistic range, from tautly realistic characters living desperate lives to head-spinning forays into body horror. To call it “unsettling” would miss the mark somewhat: this is fiction that isn’t intended to leave a reader settled. It’s also a significant stylistic departure from his previous novel, the searing noir that was Zero Saints. I spoke with Iglesias about the process of finding a structure for this book, the role of religion in his work, and how bodies factor into his fiction.
