By day, Ji-an Ha is an unassuming high school teacher-but by night, she's South Korea's top horror novelist writing runaway bestsellers of the Endless Night series. But behind her tough-sounding pen name, Ed Scar, Ji-an is actually a coward who is constantly scared by everything. Her worst fears come true when a used keyboard that she orders online somehow brings everything she writes to life, including her own original character Hades, an unhinged serial killer who ruthlessly hunts down criminals. Ji-an's only hope for survival is to make Hades love her. Can Ji-an escape her own horror novel before Hades kills her―or before she falls in love with him for real?
