Author, female, so automatically slammed (6,3,6)

I believe the answer is:

louisa may alcott

'author female' is the definition.

'so automatically slammed' is the wordplay.
'slammed' indicates anagramming the letters.
'so'+'automatically'='soautomatically'
'soautomatically' anagrammed gives 'LOUISA MAY ALCOTT'.

(Another definition for louisa may alcott that I've seen is " Female author".)
