Time travel in novel (8)
I believe the answer is:
interval
'time' is the definition.
(thesaurus)
'travel in novel' is the wordplay.
'novel' is an anagram indicator.
'travel'+'in'='travelin'
'travelin' with letters rearranged gives 'INTERVAL'.
(Other definitions for interval that I've seen before include "Break in theatre performance" , "Gap during performance" , "Space of time" , "Break, gap" , "A break as in travel" .)
