Irish author writing about individual on a bender (4,6)

I believe the answer is:

edna obrien

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

'irish author' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'about individual on a bender' is the wordplay.
'about' indicates an anagram.
'individual' becomes 'i' (Roman numeral for one).
'i'+'on'+'a'+'bender'='ionabender'
'ionabender' with letters rearranged gives 'EDNA OBRIEN'.

'writing' acts as a link.

Can you help me to learn more?

I've seen this clue in The Irish Times.
