Query: Guilty Pleasure

I usually enjoy books of substance, such as biographies, history, chronicles of discovery or classics of literature. And being a book snob, I don't usually read gothic mysteries. That said, once I opened the pages of The Historian , I must admit that I could not put it down , much like the book's protagonist, who finds a certain book very compelling. As Ms Kostova took me on an odyssey through ancient libraries and musty document rooms across Europe, her book held me in its occult spell for nearly straight 30 hours. I took breaks only for water, bathroom and quick snacks. I neglected work, family and exercise to arrive at its dusty denouement. I'm eagerly awaiting Elizabeth Kostova's next literary effort.
