I've stated somewhere before that my native language is not english

as if one couldn't otherwise tell...
To the point: I've had Dark side of the sun on my bookshelf for quite a while now, I've started it and then stopped because the language is so difficult it drives me crazy.
I'm probably asking for some starting tips, what is the book really about? What are the main topics involved? And is it really that much more difficult than the other novels (or is it just me

)?
Thanks for the answers in forehand
