A Whisker Behind (The World Behind, Book 1)

Searching for redemption in the shifting realm between the human and fae worlds, not-so-reformed fae steward Athelas seems likely instead to find death, dismemberment, and deadly magic…
Exiled, excommunicated, and with a bounty on his head, Athelas is lying low in Seoul for exactly one reason: he has a wedding to attend. Whether or not he’s welcome is another matter.
Luckily for Athelas, several bodies have turned up with their soft insides gnawed out, whether by magic or Behindkind—and the latest of those bodies is at the very wedding hall he has been staking out. The Behindkind investigators suspect one of Athelas' housemates: YeoWoo, a gumiho with a thirst for revenge and an even greater appetite for soft underbelly than Athelas. To buy herself time, YeoWoo barters alibis with the suspiciously quiet fae sharing her house, but to remain free, she must find the real murderer.
By joining the investigation, Athelas has exactly the chance he needs to prove that he is now a repentant, changed, and selfless fae, bent on atoning for former deeds…no matter how many Behindkind and humans he has to cut through to confirm that impression.
