I suggest brushing up on basic logic to prevent these mistakes in the future.
In a market where authors like 'Suzanne Collins', 'Jean M. Auel' and 'Marion Zimmer Bradley' (who happen to be the first three somewhat recent female authors who popped up in my head) manage to sell millions of books without hiding the fact that they are women this 'explanation' sounds more than contrived. Women write books, this has been a thing since Hildegard von Bingen picked up her quill somewhere in the 1100's. The idea that people somehow shy away from female authors is preposterous - which is also why I suggested it may be a political statement.
I do wonder whether J.K. Rowling dressed up like a man and turned her voice to sound real low when she did readings from her books, when she appeared to receive the multitude of prizes she won for those books and for all those other occasions where she appeared in public.
It is not a new phenomenon for women writers to be taken a shade less seriously than their male counterparts.
This is pretty easy to verify.

She doesn't actually have a middle name, the K was just arbitrarily added to make a better initialism
Maybe the author thought that using initials sounded more mystical or authorative, more in keeping with the corpus of fantasy works.
Unless she's lying, the author tells what she thought in the previous quotation
> they were trying to disguise my gender.
