The Sacred Book of the Werewolf is the tale of A Hu-Li, a 2,000-year-old Taoist werefox who plies her trade as a prostitute in modern day Moscow. By hypnotizing johns with her magical tail, A Hu-li makes men believe they are having sex with her, earns a living, and maintains her virginity. That is until she encounters and falls in love with Alexander, a high-ranking Russian intelligence officer and—not so coincidentally—a werewolf.
