Query: Audio Version Difficult for 1st Timers who have no book as reference

This audiobook might be fine as a refresher, or if you already have the book to follow along, but as a stand alone for someone who does not know the language, I found it frustrating. I need to be able to see the words. Some of the sentences after the first couple of chapters were too long for me to repeat with any success.
