A coming-of-age tale reimagined as a searing Western epic. In the small town of Sand, populated by gunslingers and surrounded by endless desert, Imma washes dishes and grieves for a life she never had. She and her brother, Nikko, dreamed of escaping to become bullet catchers, a legendary band of outlaws who can deflect bullets with their hands. But they were wiped out years ago, Nikko with them. And leaving is impossible when walking into the desert means certain death. When she sees a stranger catch a man's bullet and turn it back on him, Imma knows it can only mean one thing: the bullet catchers live on, and this is her way out. Determined to follow him, Imma starts a journey that will take her to her physical extremes and force her to question just what family means and who she really is: bullet catcher or gunslinger; hero or monster.
