An Excellent History of Elizabeth of Bathory
Strangely, this is Codrescu's only work of fiction that I can find. Certainly, it's his only non-comedic work and it excels. The reader is transported back and forth between the (then) present and medieval Hungary, a time when the ruling class did as they pleased with almost absolute impunity. While this book is definitely not for the faint of heart it is also not gory for its own sake. As far as I can find it has been out of print for some 15 years or more but is worth tracking down.
