If you are starting to read books in a foreign language, the books you start with matter. It is like wanting to run a race or marathon, you do not start right out with a big complex thing. Start smaller, less ambitiously, as a way to practice. Because if you start with something really hard and messy, you might complete it but be such a chore it will put you off reading more in the future.

Start with something shorter more manageable, less specific vocabulary. Novellas, or YA fiction, short stories.

Another tip, if you got an ebook reader, ebooks are fantastic because inbuilt dictionary or dictionaries to helo you.
