Summary:

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.

Introduction

 

She is a 21 year old adopted human, training to be a CSI; he is a 166 year old vampire, working as a personal trainer.  She knows little of her past; he knows as good as everything about his. Her parents died when she was a baby; his parents thought he died in the war. She has never fallen in love; neither has he. Then they met. Upon their first meet and first touch they feel the same; love. A feeling know yet completely unknown to the both of them.

 

 But what happens when someone from her past threatens to catch up with her? Will they be strong together, or will they be split; all alone, weak and easily destructible?

Summary:

(Mini-)Castle Ficathon '14 entry. I find myself in the presence of a being I believed to be entirely fictional. Sent on a mysterious quest not even I myself know what it's about, I land in an alternate dimension where I'll interfere with our favorite writer and cop's lives. Not very serious story, not even about itself ;) Allegedly the VERY FIRST Castle Self Insertion! Will eventually span all seasons (or so it's planned... :D)
