It depends. If you are in a region with well - developed online shopping and a large fan base of the series, it's not that difficult. As I mentioned before, Amazon usually has it. However, if you are in a more remote area or a place where the demand for such light novels is low, it might be a bit harder to find in local stores.
You can start by getting a copy of the light novel. Look for it in local bookstores or online platforms like Amazon. The first volume usually sets the stage well, introducing the main character Violet and her world.
They have some differences. The anime might adapt the story in a way that emphasizes visual and auditory elements, while the light novel can offer more detailed inner thoughts and descriptions.
One of the main themes is love. Violet's journey to understand love, both romantic and platonic, is central to the story. Another theme is the aftermath of war. It shows how people are affected by the traumas of war and how they try to rebuild their lives.
Some specialized anime or manga stores might also carry the Violet Evergarden light novel. You can search for local stores in your area. These stores focus on anime - related products, so there's a good chance they'll have it. You could also check their social media pages or call them in advance to see if they have it in stock.
