After about 200 pages, I just couldn't justify in my mind continuing. It was just boring. The prose was good, but it wasn't enough. On top of that, I couldn't keep track of all the characters. It's a bit difficult to when the author decided to call each one by different names; choose a name and STICK WITH IT.
When it comes down to it, I have a rule. When I read at night before I go to bed, if it feels more like a chore than a pleasurable experience, I start a different book. That ended up being the case with War and Peace.
