I'm working my way through a bazillion query letters as I mainline my first NYC coffee in ten days. Probably not the luckiest day to have your query letter here, but oh well.
Just a quick word about how you describe female characters: if the first or only word you use is "stunning" "gorgeous" "sex-bomb" "limber limbed" or any other description of her physical self, you've just made me reach in for the auto-no response button. I loathe this.
"Stunning physicist assassin" is almost as bad but at least there's hope she'll disfigure herself in the heat of battle.
I look for interesting compelling characters in every single book I take on. That means tell me what they DO, not what they look like.
