Query: Hard to read!

I`m Swedish and doesn't really have a hard time reading books in english.. but this one uses many words i don`t recognize and the author jumps back and forth in time!I find myself having a hard time in concentrating on the book, and i wonder if it really is necessary to describe so much environment and other happenings that i have a hard time find is relevant to this book!I get a bit confused when the author jumps back and forth in time, i don't get any good grip of the handling.
