Revised modern reading inspires international bestselling author (6,8)

I believe the answer is:

nadine gordimer

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

'bestselling author' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'revised modern reading inspires international' is the wordplay.
'revised' is an anagram indicator.
'inspires' indicates putting letters inside (inspire means to breathe in).
'international' becomes 'i' (abbreviation eg in IMF).
'modern'+'reading'='modernreading'
'modernreading' is an anagram of 'nadinegordmer'.
'nadinegordmer' going around 'i' is 'NADINE GORDIMER'.

Can you help me to learn more?

(Another definition for nadine gordimer that I've seen is " South African writer".)

I've seen this clue in The Telegraph.
