The amount of research put into this book is astounding. It's richly detailed, innovative, spellbinding, and truly chilling. It's like "The Davinci Code" meets "Dracula" full of historical twists, research, and bone chilling intrigue. It's denseness can be a little intimidating but once you get passed that it's impossible not to be hooked. The story goes back and forth between a young girl's journey to find her father and learn about his past and the father's actual account of what happened. It weaves together beautifully as they search for the real life Dracula through libraries, museums, foreign cities, and old research. Wonderfully written and imagined.
