The Historian by Elizabeth Kostova
I'm years behind, but I finally read this best seller. Actually, I listened to the audio book, which uses different actors for the different characters. It was marvelous--the accents for each character (which I don't think I would have been able to hear in my head if I read it) really added to my enjoyment of the story. And some of the voices made some scenes very eerie. The whole audio book is very well done.
This story has beautiful descriptions, interesting historical information, suspense, and a few shiver-inducing moments. You don't have to be a Dracula fan to enjoy this intelligent book. I highly recommend it.
