A State of Emergency is called due to a large amount of snowfall in the New York City area. Cars are to be off the road, and people are urged to stay in their homes. Kate Beckett can't do that though as she's at Richard Castle's.

Takes off where Writer's Block ended. 

Castle invites Kate to a Firefly party.  The story takes place in the (hopefully) not too distant future, when these two have realized that they have feelings for one another and have been on a few dates.  Other characters from the show appear and apparently, all are or will be, Browncoats (except for Martha, she just doesn't get it.)  No crime/mystery; just relationship fluff, smut and witty banter.  Although familiarity with Nathan's previous work makes the story more amusing with in jokes and dialogue, I've been told it isn't totally necessary to enjoy at least the majority of the story.  (Let me know if you disagree.)  And it's my take on how they end up in bed.

An interesting episode of a serial killer with a loving way of killing with a rose. Speaking of love, Castle and Beckett's sexual tension rises to the top. Will it overflow? Find out in "A Love Lost is a Love Gained."
