Maybe I'm naive, but I don't make my science fiction/speculative fiction choices based on the author's gender. A good book is a good book.
Some people do, though. Just ask Linda Nagata.
I don't understand how a person can go into a bookstore, look at the author's name on the cover, and think: 'Nope. She's a woman. Inferior writing inside.'
As if every man who has written a book has won awards for each book written.
Now, I admit I judge a book by its cover. It's hard not to. Book publishers put a lot of time and effort into cover art for a reason.
But I don't judge a book by its author's gender. That just doesn't make sense.
