Congrats @Saty4353! And also congrats on the JLPT N2, that’s a big achievement!
I personally find novels easier than manga, because the sentences tend to be more “completed” while in manga there are always a lot of words missing that you need to infer.
It is rough at the beginning, but then you slowly get used to the same vocab behind reused (such as verbs often used when talking, “to nod” and the like).
If you already have a bit of experience with manga, then I recommend that you try joining the Intermediate Book Club. We read a novel together, with people of varying level of Japanese. So there will be a lot of people that can help if you have questions.
Joining book clubs has always helped me a lot to make the jump and dare things I didn’t know I was ready for, so I highly recommend! Plus, you are in luck, the next book is starting in a week, and it’s free because there’s no copyright on it anymore. It is also possible to read it in your browser, which makes it easy to use Yomichan for lookups, or copy sentences in a machine translator.
So if you are interested, join here: 怪人二十面相 🦹 (Intermediate Book Club) [starting January 3rd]
