Your school or university library could be a place to find a graphic novel. Many educational institutions have a collection of graphic novels that are used for various courses or just for general reading. They may not have as extensive a collection as a public library or a bookstore, but it's still worth checking. Also, some coffee shops or cafes have a small bookshelf with books for customers to read while they're there. Sometimes you can find a graphic novel among those books.
The art style might be a turn - off for some. It could be too chaotic or not in line with one's aesthetic preferences.

Well, sometimes libraries have a collection of comics. You could check your local library. Also, some dedicated comic book apps or platforms might have it available for purchase or subscription.

You can try looking for the gorillaz graphic novel in well - stocked comic book stores. They usually have a wide selection of graphic novels, and there's a good chance they'll carry it.

Another option is to check with your local library. They may have it in their collection, or be able to order it for you. Libraries are a great resource for finding all kinds of books, including graphic novels.
