Made to read novel about leaders of Northern Europe (6)
I believe the answer is:
earned
'made' is the definition.
('earn' can be a synonym of 'make')
'read novel about leaders of northern europe' is the wordplay.
'novel' indicates anagramming the letters.
'about' is an insertion indicator.
'leaders of' says to take the initial letters.
The initial letters of 'northern europe' is 'ne'.
'read' anagrammed gives 'eard'.
'eard' going around 'ne' is 'EARNED'.
'to' acts as a link.
(Other definitions for earned that I've seen before include "Took home" , "Gained by labour" , "Got from paid employment merited" , "Merited; made" , "Merited through behaviour" .)
