And in further protest against SOPA, today I am only going to post content stolen from other blogs. So there! (and this has nothing to do with the fact that I don't have any reviews prepared)
Men's poses emphasize strength, capability, perhaps with a bit of mystery. They follow the body's natural lines and actually look like something a real person would do. Women's poses emphasize sexy sexy dangerous sex and most vary from awkward to painful to impossible. What puzzles me most about this is that studies show the vast majority of people who read novels with female protagonists are, in fact, female. Unless they're going for a very specific demographic, marketing assumes we're all cisgendered, so why are we using the cover art to objectify characters we're supposed to identify with? Posing like a pin-up is not the only way to be attractive, and twisting your body to the point of OW robs us of anything beyond "T&A." The men's poses are dynamic and interesting, implying the male characters inside are, too. So what are we saying about our female characters?
While I had often been bothered by the suggestive way women on urban fantasy covers are usually portrayed I never payed much attention to their poses, or how they differ from those of the male models, so these two posts were really eye-opening.
