Fourteen-year-old Lilith leads a typical teenage life, except for one twist: she's the daughter of the devil, residing in hell with him. Bored and eager for adventure, she strikes a deal with her father. Lilith can spend a week on Earth, but she must corrupt a good soul to evil. Should she succeed, she earns the chance to stay on Earth permanently; failure means a dreary future managing the underworld's finances. As she embarks on this mission, Lilith navigates the challenges of adolescence, temptation, and the struggle between good and evil.
