Query: A dreadfully bad book

This book was such a disappointment. After hearing all the hype, I was excited to make a new discovery. But this book is nearly unreadable. Obviously, a great deal of research went into The Historian -- but clearly not much editing. A classic case of too much information, not enough of a compelling, driving story line and characters that are boring, flat and indistinct. When more than half of a 700-page book consists of a couple of folks sitting around talking -- and it's a vampire story! -- there is a serious problem for the general reader. Sorry, it's not interesting, it's not scary, it's not suspenseful. If you're looking for middle European history and vampire legends, you'd be better off looking through the stacks for real dissertations and research. If you're looking for a good read, keep looking.
