Manga - comic; graphic novel

Its called a Graphic Novel.

There are various advantages to the medium of a comic strip. For example, they are much easier to read than a novel.

It's actually a novel. The novel is "The Mandalorian Armor" and is the first novel in The Bounty Hunter Warstrilogy.

A graphic novel is not the same as a regularly issued comic book but is a "one shot" edition that tells an original story and is not part of an ongoing narrative.

Marvel Comic's 'Revenge of the Living Monolith' is an example of a graphic novel whereas DC Comics's 'The Watchmen' is not. 'The Watchmen' is an example of a trade paperback due to it being a collected version of the limited series that was first released in comic book form.
