Absolutely. Christos ' character was strong and off-putting in some of the same ways that Kathryn's was. She was powerful, sarcastic, a diva in ways similar to Christos, but she was treated as a sexual object differently than Christos was treated. Some of this was part of who she was, but it was enhanced in the style of her performances with The Wonders, and in the way her first husband used her to his gain.
She also suffered abuse in her life, was seen as weaker, and I think that the climactic shift toward the end of the book would have gone down differently had Christos or Leon been chosen.
As a woman, I connected with Kathryn because she is at times snarky, at times comforting, and she sees herself as beautiful now, when she felt anything but that before The Wonders.
