When assembling a short story collection, some editors start with a theme or a concept. And if they do start with a specific setting, it’s usually one that’s already established, like the fictional universes of Star Wars or the Halo games. But for the new sci-fi short story anthology Many Worlds: Or, The Simulacra (paperback), co-editors Cadwell Turnbull and Josh Eure have created a new universe — or, more accurately, a new multiverse — which their contributors are helping design through their short stories. In the following email interview, Cadwell and Josh discuss what inspired and influenced the assembling of this anthology, and the construction of this universe.
