Resume novel -- gripping page is outstanding (7)
I believe the answer is:
supreme
'outstanding' is the definition.
(thesaurus)
'resume novel gripping page' is the wordplay.
'novel' is an anagram indicator.
'gripping' indicates putting letters inside.
'page' becomes 'p'.
'resume' anagrammed gives 'sureme'.
'sureme' enclosing 'p' is 'SUPREME'.
'is' is the link.
(Other definitions for supreme that I've seen before include "Highest in rank - incomparable" , "topmost level" , "creamy dish of chicken perhaps" , "God" , "Most excellent" .)
