The God and the Gumiho (Fate's Thread Book 1)

Kim Hani, once known as the Scarlet Fox, has retired from consuming souls and now works at a coffee shop in the mortal realm. There she regularly antagonizes Seokga, a trickster god exiled from the heavenly kingdom of Okhwang, who is working toward his redemption. When a powerful demon escapes from the underworld and threatens humanity, Okhwang's emperor offers Seokga a deal: kill the rogue demon and the legendary Scarlet Fox, and he will be reinstated as a god. Hani, determined to protect her identity, proposes a partnership—she will assist Seokga as his investigative partner while secretly undermining his efforts to discover who she really is. Together they will stop the demon, but Hani has no intention of being caught. As the bickering pair pursue their investigation through violence and chaos, they find themselves drawn to each other. Their partnership forces them to confront whether they can work together to prevent an apocalypse, or if their secrets will destroy them and the world.
