This writer's books around store due out soon (8)
I believe the answer is:
imminent
'due out soon' is the definition.
I can't tell whether this defines the answer.
'this writer's books around store' is the wordplay.
I cannot quite understand how this works, but
'writer's' could be 'im' ('I am' referring to the writer of the clue) and 'im' is found in the answer.
'books' could be 'nt' (abbreviation for New Testament) and 'nt' is found in the answer.
'store' could be 'mine' (I've seen this before) and 'mine' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for imminent that I've seen before include "Looming or impending" , "Likely to happen at any moment" , "About to happen very soon" , "Approaching fast" , "About to occur, any time now" .)
