Ten years ago, four members of the Blackfeet Nation tribe did something that haunts them still: On forbidden lands, the friends hunted and killed a pregnant elk. Novelist Stephen Graham Jones, himself a Blackfeet, has spent decades weaving Indigenous American mythology into spellbinding works of horror. He is at his most masterful here, as he traces the mystical, gory violence that follows when the spirit of the elk—a mythical creature in the tribe’s tradition—takes its revenge.
