Yes, there are many novels with the theme of the walking dead. I recommend the two books, The Road to Resurrection is So Difficult and A Cameo in the Walking Dead. The former was about the protagonist crossing different worlds to find the soul fragments of his dead lover. It was a fantasy romance novel. The latter was a poacher who traveled through the world of the walking dead and interacted with the characters in the original play. It was a light novel-derivative doujinshi novel. I hope you like this fairy's recommendation. Muah ~😗
