If we're looking for new directions....Maybe it should be EL's next move. 50 Shades of Gay.
Fifty Shaves of Grey. (There might be a variety of shavers. I'm sure one or two here would imagine Loras- or Renly-lookalikes wielding the razor....)
Fifty Shales of Grey, the tale of an activist against the exploitation of shale oil in Canada, whose sexual conquests scandalise the world, leading to extradition requests and the seeking of asylum.
Fifty Shades of Cray, describing the high-octane, not to say technicolour, romantic exploits of a completely colour-blind marine biologist.
