Susie is diverted by this publication (5)
I believe the answer is:
issue
'this publication' is the definition.
(synonyms)
'susie is diverted' is the wordplay.
'is diverted' is an anagram indicator (each letter get diverted elsewhere).
'susie' anagrammed gives 'ISSUE'.
'by' is the link.
(Other definitions for issue that I've seen before include "Argument" , "something to discuss" , "Offspring; problem" , "litter" , "Question in dispute to be settled" .)
