A new house featured in the writer's story (7)
I believe the answer is:
ivanhoe
'story' is the definition.
(Walter Scott novel)
'a new house featured in the writer's' is the wordplay.
'a new' becomes 'an' (I've seen this in other clues).
'house' becomes 'ho' (abbreviation for house).
'featured in' is an insertion indicator.
'the writer's' becomes 'ive' (the writer of the crossword).
'an'+'ho'='anho'
'anho' put into 'ive' is 'IVANHOE'.
(Other definitions for ivanhoe that I've seen before include "Walter Scott's eponymous hero" , "Sir Walter Scott novel" , "Scott's Crusading hero" , "one Rowena loved" , "romance" .)
