Stroller getting it in Time Books (9)
I believe the answer is:
itinerant
'stroller' is the definition.
(thesaurus)
'it in time books' is the wordplay.
'time' becomes 'era' (era is a kind of time).
'books' becomes 'NT' (abbreviation for New Testament).
'it'+'in'+'era'+'nt'='ITINERANT'
'getting' acts as a link.
(Other definitions for itinerant that I've seen before include "(Person) on the move" , "Tie-in rant to a traveller" , "Nomad" , "Wandering from place to place" , "Moving from place to place" .)
