There's no surprise for people to find it hard or boring to read novels for the first time because of how the authors describe their story very different and beyond our minds that we possibly can never think of.
Why not read something simple but descriptive, making your mind functions a bit to catch up. You can grab a dictionary when stumble upon a word that you never encountered before - who knows you can make your teachers dazzle with your outstanding use of words.
Back to the topic, reading novels or anything contains letters are really great - not just understanding the story or situation, but also sharing your ideas when it comes to writing or learning new languages unintentionally. It opens us the creative mind of thinking, expanding our thoughts and opinions to a better view. Not only that, it helps us to improve our vocabulary and train us to read more each day without the need to complain, whether if it's a reference book, an article or even the news on the television.
Find the bright side, I'm sure you can read and finish the novel you picked.
