Sim Kern is a Gulf Coast author and environmental journalist. Their debut horror novella, Depart, Depart!, was selected for the Honor List for the 2020 Otherwise Award, and their short story collection, Real Sugar is Hard to Find, was hailed in a starred review by Publishers Weekly as, "a searing, urgent, but still achingly tender work that will wow any reader of speculative fiction." As a journalist, they report on petrochemical polluters and drag space billionaires.

Sim spent ten years teaching English to middle and high schoolers in Houston, Texas, before shifting to writing full-time. They live near Brays Bayou with their spouse, two kids, and a very good dog.
