I already am suspicious of books over 500 pages. This book is nearly 650 pages, and I couldn't get into the book until about page 200! Kostova's "literary thriller" reads more like a plodding travelogue that strains to tie together interesting tidbits about Dracula and vampires in general.
Here is the only quote that stood out for me:
History has taught us that the nature of man is evil, sublimely so. Good is not perfectible, but evil is.
This is Dracula trying to persuade a historian to catalogue his vast library which documents the evil acts of man. I don't think I'm giving too much away because Kostova doesn't really run with this theme. Which is a shame, really, because I never thought of evil - and not goodness - being perfectible.
