Gift of story books (6)
I believe the answer is:
talent
'gift' is the definition.
(synonyms)
'story books' is the wordplay.
'story' becomes 'tale' (synonyms).
'books' becomes 'NT' (New Testament).
'tale'+'nt'='TALENT'
'of' is the link.
(Other definitions for talent that I've seen before include "Natural aptitude or skill" , "Dull means claw" , "Type of scout - innate ability - old Greek money" , "Flair, aptitude" , "Natural ability or flair" .)
