Continue concerning novel (5)
I believe the answer is:
renew
'continue' is the definition.
(thesaurus)
'concerning novel' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'novel' becomes 'new' (similar in meaning).
're'+'new'='RENEW'
(Other definitions for renew that I've seen before include "Give fresh strength to" , "Reform" , "Restore, resume" , "Transform born-again" , "Update library book, acquaintance, etc" .)
