"Enchanting fantasy . . . With an intoxicating mix of action, mystery, and deliciously angsty romance, this reads like the most bingeable K-drama."--Publishers Weekly (starred review)

Kim Hani has retired from a life of devouring souls. She is, simply put, too full. Once known as the infamous Scarlet Fox, she now spends her days working in a coffee shop and annoying a particularly irritating, if unfairly handsome, trickster god as often as she can.

That god is Seokga the Fallen. Exiled from the heavenly kingdom of Okhwang, he now begrudgingly resides in the mortal realm, working toward his redemption and suffering through his interactions with the particularly infuriating, if sneakily charming, gumiho barista at his favorite café.

But when a powerful demon escapes from the underworld and threatens to end all of humanity, Okhwang's emperor offers Seokga an enticing bargain: Kill this rogue creature, as well as the legendary and elusive Scarlet Fox, and he will be reinstated as a god. Hani, however, has no intention of being caught. Seokga might be a trickster god, but she has a trick of her own that he'll never see coming: teaming up. As Seokga's assistant, Hani will undermine and sabotage his investigation right under his overly pointy nose. Sure, she'll help him kill the demon, but she certainly won't allow him to uncover her secret identity while they're at it.

As the bickering partners track their case down a path of mayhem and violence, the god and the gumiho find themselves inescapably drawn to each other. But will the unlikely couple stand together to prevent the apocalypse, or will they let their secrets tear them--and the world--apart?
