This thread I just saw, bought the thingy for kindle and love it.
The Two Queens ending is my favorite so far. That and where she takes Reemek and the Orks back home to rebuild.
Romance books often have just as detailed sex scenes. Normally at least a couple, sometimes a couple more extra. Such as Fashionably Dead. Of course, the story is the focus and thatis where all the romance subgenres come in. For instance, Romance SteamPunk.
Anyhow, the 'problem' with sales is more a matter of missed opportunities, instead of lack of interest, believe do I.
