Children of one magazine (5)
I believe the answer is:
issue
I believe this is a double definition.
'children' is the first definition.
(issue can mean someone's offspring)
'one magazine' is the second definition.
(I've seen this before)
'of' acts as a link.
(Other definitions for issue that I've seen before include "Result - children" , "Publish - put into circulation" , "Outcome - discharge" , "Important topic for debate" , "Put out; topic for discussion" .)
