Query: Very Challenging To Follow

I found this book hard to follow. I was constantly having to look up the meaning of various words (many of which are not in the Kindle dictionary). Might just be me...There are a lot of parallel tracks to follow in this book. Went to see the movie thinking it would be easier to track on, but found it almost as confusing as the book.
