Broke? That's new in struggling novelist (9)
I believe the answer is:
insolvent
'broke?' is the definition.
(thesaurus)
'new in struggling novelist' is the wordplay.
'new' becomes 'n'.
'in' is an insertion indicator.
'struggling' indicates an anagram (I've seen this in other clues).
'novelist' is an anagram of 'insolvet'.
'n' put inside 'insolvet' is 'INSOLVENT'.
'that's' acts as a link.
(Other definitions for insolvent that I've seen before include "In the red" , "Unable to pay debts owed" , "on the rocks" , "Snivel not, although you are bankrupt!" , "strapped for cash" .)
