I have read it, and I loved it! I can still remember a lot of the characters and their lives, even though it has been over 4 years since I read it.
I was lucky enough at that point in my life to be single, without kids, and living in a country where I didn't speak the language - so I had a lot of time to really become engrossed in it! I was working but I had a lot of free time and on my days off I would often spend them doing nothing but reading, especially if the weather was poor. As you can see I have very fond memories - but I'm not sure if they were from the book itself, or the freedom that I had to read it through without interruption! These days I can barely read a chapter without something coming up
It is a very long, very involved, and very complex story line and I think it is hard to set a book like that down, and even harder to pick it back up. But if you do, you won't be disappointed.
