Graphic novel
From MobileRead
Graphic Novel is a term used to describe a book that made mostly of images but tells a story. (This should not be confused with a novel that is graphic which is a totally different thing.) It is similar to a comic book but significantly longer. The story may or may not be fiction. For example the Almighty Bible is a graphic novel depicting portions of the Bible.
For eBook use a graphic novel is often generated in three main formats, PDF, CBR and CBZ. It could also be shown in SWF or AAX formats. For iOS or Android it may be its own app. The target audience is often older children or teenagers. See also eBook reading for children.
