I don't know who the author of 'the house without windows novel' is. There are so many novels out there, and without more context, it's difficult to determine the author.
I'm not sure specifically as there could be many novels with this title or a similar concept. It might be about a very enclosed, isolated place, perhaps a metaphor for a person's inner self that is cut off from the outside world.
Well, the 'House Without Windows Graphic Novel' might tell a story that is set in a rather unique and somewhat eerie environment. A house without windows can be seen as an abnormal and uninviting place. It could be that the story follows the experiences of those who enter or are affected by this strange house. There might be elements of the supernatural, as such an odd structure could be a home to otherworldly things. Or it could be a metaphor for a character's internal state, like a closed - off mind or a heart that doesn't let the outside world in.
It might make the house feel isolated and cut off from the outside world. This could create a sense of confinement and mystery for the characters and readers.
You can use light - colored curtains for the big windows. They can soften the strong sunlight and add a touch of elegance to the room. Also, placing some potted plants near the windows can create a fresh and natural atmosphere.
It would probably look very modern and stylish. The contrast between the white of the house and the black windows can create a striking visual effect. It might give an impression of simplicity and elegance at the same time.
I don't know the exact main characters in this graphic novel since I haven't read it. But they could be people who are somehow connected to the house without windows, like the owner of the house, or someone who is trapped inside it.
The theme of alienation could be in it. If there are no windows, it's as if the inhabitants are cut off from the normal world, and the characters may experience a sense of not belonging. Another theme could be transformation. Maybe within the walls of this windowless house, the characters go through significant changes, like a chrysalis. There could also be a theme of longing. Longing for the outside, for connection, for something more, which is emphasized by the lack of windows.
If we assume the laughing king is a character in a fantasy world, he might be a king who has had a strange encounter that made him laugh constantly. For example, he could have met a magical joker who cast a spell on him. Or he could be a king who was born with a condition that makes him laugh involuntarily, and this has led to various adventures and misadventures in his kingdom as his subjects try to understand and deal with their unusual king.
