"I am looking for the artful way any given story is conveyed," writes Roxane Gay in her introduction to The Best American Short Stories 2018, "but I also love when a story has a powerful message, when a story teaches me something about the world." The artful, profound, and sometimes funny stories Gay chose for the collection transport readers from a fraught family reunion to an immigration detention center, from a psychiatric hospital to a coed class sleepover in a natural history museum. We meet a rebellious summer camper, a Twitter addict, and an Appalachian preacher--all characters and circumstances that show us what we "need to know about the lives of others."
