What did the 'slut' character do?

Yeah, I want to know.

What did the "slut" character do to deserve that title, you can see it in the extended cast list.

To name a character like that might give a clue as to the attitude and maybe the agenda of the storytellers.

I can scarcely believe that a woman novelist would label in such a way. Or did she?

Anyone who has read the book may have an answer too.
