Innovative literary work? (5)
I believe the answer is:
novel
This clue is a double definition.
'innovative' is the first definition.
(I've seen this before)
'literary work?' is the second definition.
(novel is a kind of literary work)
(Other definitions for novel that I've seen before include "New piece of fiction?" , "Paperback" , "book such as Brave New World" , "Previously unknown" , "piece of writing" .)
