Query: Has potential, but needs an editor

The Historian takes a potentially interesting plot and drags and drags it out until you just have to put the book down out of boredom. I agree with the other reviewers that this book badly needed better editing, as the action could have been truly fast paced and hooking and the flashbacks would not have been that confusing and dragged out. The ending is also a bit anticlimactic, as I, for one, was expecting a vampire and ended up with a librarian. At that point I wanted to throw the book across the room. After enduring looooong (but admittedly well-written) descriptions and travels covering half of Europe and multiple people, all we get is a librarian who is biting and scaring people in order to help him with his 'collection'. Ooookay.
