I just finished an awesome Supernatural Fanfic called "Cas, you had a baby?" I'm now reading the sequel, Mary's Kitchen, and they are both amazing, even if you don't watch Supernatural. The writer in amazing with words, and there is the perfect amount of fluff, action, and smut ;). There is a little more fluff than action at the beginning.

Sam: Yeah? When I told Dad I was scared of the thing in my closet, he gave me a .45.
Dean: Well, what was he supposed to do?
Sam: I was nine years old. He was supposed to say, "Don't be afraid of the dark."
Dean: Don't be afraid of the dark? What, are you kidding me? Of course you should be afraid of the dark! You know what's out there!
