Query: Unforgettable

Let me start by saying that the first 7 or so pages are difficult to get through. After that it is pure magic! I, too, was challenged to read this book by a co-worker who said he'd found very few people who had finished it. Well, of course, I couldn't turn down that sort of challenge. What I couldnt' have predicted was how much I would enjoy it. Yes, Eco is full of himself at times, and yes, I did have my dictionary next to me (which by the way I have about 20 words that I've never been able to find in ANY dictionary) but, you have to admire the genius at work, here. Plus, it was just an enthralling subject matter.
