In the dark alleys of 1920s Gyeongseong, a monster is born not of nature, but of human greed. Lee Kang, the "wailing tiger," is a failed experiment created by his own traitorous father. Every time he unleashes his beastly power, his bones shatter in agonizing pain. His only anchor is Yeon-hwa, a mute shaman girl who sacrifices her own life force to keep his soul from slipping into madness. To save the girl and crush the empire that turned him into a monster, Kang must rewrite the history of a failing nation. He will turn the streets of Gyeongseong into a sea of blood. "I will not die a failure. I will die a nightmare."
