In Sunpo, nobody gets out alive.
A year ago, assassin Shin Lina botched a mission and her entire beloved street gang was murdered. Their deaths still weigh heavy on her, and worst of all, she’s now forced to work for the rival gang’s leader, Kalmin. The very man who killed the Talons.
When Kalmin gets abducted for stealing a priceless tapestry, it’s up to Lina to rescue him. If she doesn’t, the gang kills her sister. The job sounds simple—but then she finds out Kalmin scorned the infamous Piper—the magical flute-wielding emperor of an immortal goblin folk that used to rule over humanity. The enigmatic Dokkaebi king isn’t more than a scary campfire tale to Lina—until he shows himself to her, offering a bargain: kill him and Kalmin walks free.
It seems absurd, but she soon realizes that the cunning Piper, grown weary and bored over the centuries, thinks it’s all a fun game. Lina is determined to kill him regardless. But what she doesn’t expect is for his charm to enchant her too…and there’s no happy ending for anyone who falls for the goblin king.
