To me, the original cover focuses on being fully woman. To me, it connotes being true to oneself. A deeper look.
The replacement cover focuses on being a particular kind of woman. To me, it connotes kind of a manipulative type [it hearkens to "Mrs. Robinson" for me]. A shallower look. Reading the excerpts, I feel the deeper look is where the book really comes in at... now watch me be wrong

. Your partner's preference is a good sign on my not being that, though

.
[Now, granted, some ~ one in particular... oh, hi g...

] might jump in and say that being manipulative is a woman's trait, as well, perhaps even the overriding one

... but the original [albeit maybe more "erotica" is a healthier kind of take on "woman" to me... and, hopefully, that erotic sense of who we are gets more expression than any manipulation does].
Well, not sure if I've clarified anything here, or just muddied the waters... all said, I'm glad to hear that your partner agrees with me. The original is certainly a more visually compelling cover than the latter! I would think that a brief quotation printed on the front, or the first thing on the back, could easily work to place the book in its more proper category for any potential reader.
WoW... the prices you find yourself forced to deal with, eh?
