Finished Neuromancer, started The Da Vinci Code

I finished reading Neuromancer, and I'll start reading The Da Vinci Code.

I finished reading Neuromancer. Actually, I wasn't able to understand even the rough story because the English difficulty is a little high for me. So I read it aloud in my mind from the middle of the story and finished it. In English learning perspective, it will be O.K. even though I can't understand the whole contents.

But reading books without understanding is becoming very tough for me. So I'll read The Da Vinci Code next. I was able to enjoy Origin, the same series by Dan Brown, and I guess that I can understand the book.
