Fetch book round (5)
I believe the answer is:
bring
'fetch' is the definition.
('bring' can be a synonym of 'fetch')
'book round' is the wordplay.
'book' becomes 'b'.
'round' becomes 'ring' ('ring' can be a synonym of 'round').
'b'+'ring'='BRING'
(Other definitions for bring that I've seen before include "Carry (to a place)" , "Convey" , "Conduct" , "Cause to exist" , "Transport" .)
