Perfect example of a story book, about to be banned (7)
I believe the answer is:
epitome
'perfect example' is the definition.
(I've seen this before)
'a story book about to be banned' is the wordplay.
I cannot really understand how this works, but
'book' could be 'tome' (a tome is a book) and 'tome' is found in the answer.
This may be the basis of clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for epitome that I've seen before include "classic example" , "Paradigm" , "Exemplar - embodiment" , "Embodiment or perfect example" , "Summary; embodiment" .)
