I was late on this one, and it's great, because I could vote for the last one :
I don't care about the author's gender, and I've no idea what ratio my books have.
If I consider by genre :
- a majority of female romance authors (declared, as it seems some male ones write behind a female pseudonym
),
- a majority of male authors for Sci-Fi
- a majority of female authors for fantasy
- a 50/50 for thriller/crime
But this can change very rapidly, as when I discover an author that I really like, I have a tendency to buy all his/her writings while I am at it !
