Query: Lust, Valour, Passion Make a Crossover Vampire Hit

In his premier novel, Vampire Vow, Michael Schiefelbein has employed the conventions of gothic fiction with wit, passion, and intelligence, a combination that will render his book a crossover success because these qualities will appeal to a wide range of readers, including those (like me) who would not normally read vampire novels. Vampire fans will relish the renate lore; gay readers, the homoeroticism; scholars, the clever exploration of philosophical and theological themes. The sly Dr. Schiefelbein has produced (without being explicit about it) a debate between Christ and Nietzche's Anti-Christ, in the role of the novel's protagonist and uebermensch, Victor Decimus. Leaving the crypt door open for a sequel, the novel delivers tight plotting, vivid characterization, and demonic romanticism. --Thomas L. Long, Editor, Harrington Gay Men's Fiction Quarterly
