So her defeating huge groups of enemies, ripping open space-time, conjuring intense storms, and kicking armed men in the 'nards is "helpless"?
I'd hate to meet a woman you consider capable!
I'm digging the folded open cover, showing Booker on front and Elizabeth on the back. Of course the cover was handled with marketing input--every cover goes through marketing. It has to have mass appeal. The solution is to give hardcore fans, who don't need convincing, something special when they preorder the collector editions.
EDIT: Or make the cover reversible. Print it so those who want Elizabeth (or Songbird, or a combination) on the front can just turn the cover inside out.
