What pen name sounds best?

So far I've come up with:
Sierra Cross
Sarah Morganson
Morgan Faith

Any more ideas? Which do you prefer? I focus mostly on drama/thriller/horror/fantasy/and historical based work with dark themes.

Sierra Cross.

I think Sierra Cross sounds best, but you might want to do some internet searches and make sure someone else isn't already using these names.

I like Morgan Faith the best, but Sierra Cross is good too.
