The Sunken Mall is a novella in The Tarot Sequence, a fantasy series by KD Edwards. The novella was self-published as a free story for fans on May 5, 2020, and uploaded to a Google Drive folder. Edwards had announced the original concept for the story in late 2019, and began sharing each chapter as it was completed, before ultimately deciding to publish the novella in its entirety on a dedicated release date.
Edwards ran a cover design contest, with a winner chosen by a 5-person panel. Alex Yu-Chi Wang designed the winning entry, but all submissions were included at the start of the novella.
