"The "Graphic Novel" is a format, not a genre. Graphic novels can be fiction, non-fiction, history, fantasy, or anything in-between.
Graphic novels are similar to comic books because they use sequential art to tell a story. Unlike comic books, graphic novels are generally stand-alone stories with more complex plots. Collections of short stories that have been previously published as individual comic books are also considered graphic novels."
