@Ed Costello has a real talent for character work. Maybe it's the fact that many TLs in the traditional sense are focussed on male characters,* but I find Ed particularly skilled at writing his female characters.
Now, somebody could very well say that a human is a human, and it should't be any different to write a female character. Well, I have two possible answers. Either it is different, and many AH writers fail to grasp it, or it's not, but many AH writers fail to grasp that fact. I suspect that AH is a far more male dominated writing space than most, and assume that this fact has an impact, but I could be talking through my hat.
*monarchies, battles, wars, politics, have all been generally male dominated, so exploring how they might be different often concentrates on the males who dominated their TL, or could have done, had things been different.
