The Historian Initial Thoughts

Well I've started reading The Historian by Elizabeth Kostova. I'm about a third of the way through it and I'm a little disappointed. Don't get me wrong, it's a good story and it moves a long at a decent clip but I keep getting the sense that this was a book written by committee. As if there is a formula that was followed in it's writing. I've also noticed that the dialog doesn't sound very natural or distinctive between the characters. These are all minor things yet I find they distract me from the story more than they should. Perhaps my opinion will change once I've finished it. I'll post I follow up once I've done that.
