Triggering literary work upset one's following (7)

Ross

I believe the answer is:

emotive

I'm a little stuck... Click here to teach me more about this clue!

'triggering literary' is the definition.
I can't judge whether this definition defines the answer.

'work upset one's following' is the wordplay.
'work' becomes 'tome' (tome is a kind of work).
'upset' shows that the letters should be reversed in order.
'one's' becomes 'ive' ('one has' can mean 'I have').
'following' is a charade indicator (letters next to each other).
'tome' written backwards gives 'emot'.
'emot'+'ive'='EMOTIVE'

Can you help me to learn more?

(Other definitions for emotive that I've seen before include "Deeply felt" , "Stimulating to feelings" , "able to get going" , "Arousing intense feeling" , "Move tie (anag)" .)
