Crossword Genius

One converting to book form, turning over lines (9)

Ross

I believe the answer is:

noveliser

'one converting to book form' is the definition.
(eg someone who turns a film into a novel)

'turning over lines' is the wordplay.
'turning' indicates anagramming the letters.
'over'+'lines'='overlines'
'overlines' is an anagram of 'NOVELISER'.
