Eighteen-year-old Gu Miyoung has a secret. She's a gumiho-a nine-tailed fox who survives by consuming the energy of men. But she's also half-human and has a soft spot for people. So she won't kill indiscriminately. With the help of a shaman, Miyoung only takes the lives of men who have committed terrible crimes. Devouring their life force is a morbid kind of justice... or so she tells herself.

But killing men no one would ever miss in bustling modern-day Seoul also helps Miyoung keep a low profile. She and her mother protect themselves by hiding in plain sight. That is until Miyoung crosses paths with a handsome boy her age as he's being attacked by a goblin in the woods. She breaks her mother's cardinal rule--revealing herself and her nine tails--to save Jihoon from certain death. In the process, she loses her fox bead--her gumiho soul. Without it, she will die.

When Miyoung and Jihoon next meet, there's no doubt they are drawn to each other. But their tenuous romance could be over before it even begins, as Miyoung's efforts to restore her fox bead by the next full moon ensnares them in a generations-old feud, forcing Miyoung to choose between her immortal life and Jihoon's.

An enthralling tale inspired by Korean folklore and set in a rich contemporary fantasy world, Gumiho is an absorbing love story that heralds the arrival of an exciting new voice in YA.
