Domination/Submission and possibly BDSM--Beware this author writes some graphic sex scenes!
 
Beauty and the Beast--To sleep and dream in alien sexual slavery ....  In stasis, Sadie was being trained as a submissive for her new life via computer simulation when something went terribly wrong.
 
Fortunately for Sadie, she'd become Krull's obsession and he was willing to go through whatever it took to have her.  Unfortunately for Krull, Sadie wasn't convinced she wanted the alien beast man to rescue her--in fact, she was pretty sure she didn't.
 
But Krull decided, if he had to chase her halfway across the alien world to give her his love, so be it!
