twilit

Fanfiction-like works of original literature. Stories or novels bordering between being works of original literature and fanfiction of other literature.

Etymology: A double entendre for one of its prime examples, the novel series Twilight, criticized as being an original work of fiction with fanfiction-like refereces to pre-existing works most notably from Anne Rice.
