Gift of a story book? (6)
I believe the answer is:
talent
'gift' is the definition.
(synonyms)
'a story book?' is the wordplay.
'a story' becomes 'tale' ('tale' can be a synonym of 'story').
'book?' becomes 'nt' (I've seen this in other clues).
'tale'+'nt'='TALENT'
'of' acts as a link.
(Other definitions for talent that I've seen before include "Skill, natural ability" , "Innate ability or Biblical money unit" , "some scouts are looking for" , "Sort of scout - old money - gift" , "Clever folk" .)
