New fiction? (5)
I believe the answer is:
novel
This clue is a double definition.
'new' is the first definition.
(similar in meaning)
'fiction?' is the second definition.
(novel is a kind of fiction)
(Other definitions for novel that I've seen before include "Book of prose fiction" , "Previously unknown" , "Unusual; book" , "Volume of prose fiction" , "piece of writing" .)
