Revive, concerning novel (7)
I believe the answer is:
refresh
'revive' is the definition.
(I've seen this before)
'concerning novel' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'novel' becomes 'fresh' (both can mean new).
're'+'fresh'='REFRESH'
(Other definitions for refresh that I've seen before include "brace" , "give life again to..." , "Enliven once more" , "perk up!" , "Give drink to" .)
