Hmmm ... (going back and re-reading the rules) ... There wouldn't be a loophole in this where a dash of science fiction could peak through? Perhaps something like travelling through time? Picture H.G.Wells time machine in the back of the cover, or perhaps (dare I say it ...) the 'Enterprise' hovering low in the sky with a Kirk-like person (complete with uniform) wooing a local maiden fair? ... LOL!!! Sorry about the joke, (I'm a techie) but it just struck while reading through the thread here! (I've read a few of romance type books in my dark past, so do know what the theme really is;-) BTW: finding example covers to get the general idea from is just a google search away. Save the poor store clerk some stress:-) (Found one site with Fabio based covers already - http://www.fabioifc.com/BOOKCOVERS/FabioCovers.html)
