A novel affair? (7)

I believe the answer is:

romance

I believe this is a double definition.

'a novel' is the first definition.
(romance is a kind of novel)

'affair?' is the second definition.
(thesaurus)

(Other definitions for romance that I've seen before include "Novel - affair" , "Sentimental affair in Menorca" , "Affair of the heart" , "Language group; love affair" , "mysterious quality" .)

I've seen this clue in the Evening Standard and The Globe and Mail.
