Sweet Cheese! I have never been so conflicted with so many interesting plot ideas. Normally it is just one in a list. I love playing the alien/mutant/creature. To have someone who really wants to play the human against that is a real treat. I love romance, but do not want to write smut. Instant love is not my cup of tea.

-The Hive 
Is there a specific alien race in mind? Or do I get to use one of mine?
-Identity 
Not totally sure on this one. I can see some fun for a while, then getting old fighting over the same body. 
-The Ghost, The Gunman, and the Grim 
Unless you are already doing this one of course.
-Mutagen 
I am not one hundred percent sure I can do this. I have never written a person madly in love. I think it would be interesting. 

Do you need a sample of writing? If so, I will happily supply.
