Graphic Novel
Story told in panels as much as sentences.
A graphic novel tells the story in pictures and words together, and if you are writing one you are writing a script for that partnership, not a prose novel with illustrations to come later. What the panel shows, what it refuses to show, and what the reader understands in the gutter between panels is part of the writing. A speech bubble that repeats the drawing is usually a waste of both.
The genres inside graphic novels are as wide as any other shelf, from memoir to fantasy to a story about ordinary work. Think in scenes you can see, and in pages that have a shape. Dialogue has to be short enough to live in a balloon and exact enough to carry character. You don't have to be the person who draws it, but you do have to leave the artist something real to do. Describe what matters in the frame, and don't choke the page with directions that are really you refusing to trust the picture.
The kinds of book inside it
Autobiographical
A life is told in images as well as recollection, and the visual metaphor should clarify memory rather than pretty it up.
Fantasy
Worlds that would take chapters to describe can arrive in a panel, so spend the words on character and the rules the pictures can't explain alone.
Literary
Quiet stories work in this form when the imagery is doing emotional work, not when the book is embarrassed to be a comic.
Superhero
Power and responsibility are the old engine, and a new book needs a specific person inside the costume, plus a reason for the fights.
