New city story (7)
I believe the answer is:
novella
'story' is the definition.
(I've seen this before)
'new city' is the wordplay.
'new' becomes 'novel' (similar in meaning).
'city' becomes 'LA' (Los Angeles).
'novel'+'la'='NOVELLA'
(Other definitions for novella that I've seen before include "story, short one" , "Small book" , "piece of fiction" , "Short fictional piece" , "short book" .)
