Can’t recall title of 90s audiobook

This would be mid to late 90s. Book was on cassette(s) and was purchased at a discounter in 1998 (which is why I’m guessing it was released a little earlier). I also remember NPR had done an interview or review on the book(possibly with the author). Book was fiction, I remember the discussion was about an Iron Maiden type or steel hanging cage / torture device, and possibly female vampire…. Any help appreciated!
