Leading author reviews the story you made somewhat pretentious (5)
I believe the answer is:
artsy
'somewhat pretentious' is the definition.
'artsy' can be an answer for 'pretentious' (I've seen this in another clue). I am not certain of the 'somewhat' bit.
'leading author reviews the story you' is the wordplay.
'leading' indicates taking the first letters (the leading letter of the word).
The initial letters of 'author reviews the story you' is 'ARTSY'.
'made' is the link.
Can you help me to learn more?
(Another definition for artsy that I've seen is " pretentious".)
