Published fiction, incorporating new draft (7)
I believe the answer is:
outline
'draft' is the definition.
('outline' can be a synonym of 'draft')
'published fiction incorporating new' is the wordplay.
'published' becomes 'out' (I've seen this in other clues).
'fiction' becomes 'lie' (I've seen this before).
'incorporating' means one lot of letters goes inside another.
'new' becomes 'n'.
'lie' going around 'n' is 'line'.
'out'+'line'='OUTLINE'
(Other definitions for outline that I've seen before include "Profile" , "General plan; summary" , "Preliminary draft" , "Sketch or contour" , "General plan; sketch" .)
