Brilliant story, with editor accepting books (8)
I believe the answer is:
talented
'brilliant' is the definition.
(I've seen this before)
'story with editor accepting books' is the wordplay.
'story' becomes 'tale' (synonyms).
'with' is a charade indicator (letters next to each other).
'editor' becomes 'ed'.
'accepting' means one lot of letters goes inside another.
'books' becomes 'nt' (New Testament).
'tale'+'ed'='taleed'
'taleed' enclosing 'nt' is 'TALENTED'.
(Other definitions for talented that I've seen before include "Clever" , "Well-endowed with gifts" , "Having a natural aptitude or skill" , "Having an unusual amount of ability" , "Skilled" .)
