The unknown. You don't know what's inside the closet. It could be a monster, a ghost or something equally terrifying. It plays on our fear of the unseen.
Well, a closet novel is basically a literary work that an author creates but decides to keep hidden away. It could be because they're not confident about sharing it, or it might be too personal. Sometimes these novels are never seen by anyone else.
The Fourth Closet is classified as a graphic novel. It typically features detailed and dynamic illustrations that enhance the narrative and draw readers into the story world.
