Kate Beckett has personal experience when it comes to dealing with a nine year old on a sugar rush.

Castle is backing off the sexual innuendo, letting Kate know he'll always be there. Kate is silently seeking and accepting more. A little back and forth. Chapter 52 up 03/19/12! *Reposted 3/20 due to FFnet errors.

AU. Detective Kate Beckett is separated and raises her son alone. She meets Richard Castle by accident, literally, on the tenth anniversary of her mother's death, turning her life upside down.

They have a deal.

A frustrating case, a victim with more enemies than friends, mob ties, gangs and something neither saw coming. When Castle and Beckett find they are being hunted, will it drive them closer or push them further apart? Rated M for Chapters 35 and up.

Kate is given guardianship of a friend's one-year-old daughter. Castle tries to help in his own unique way. Chaos and fluff ensues.

A series of season four episode additions that often become thematic extrapolations. All Castle-Beckett flavoured. Currently: 409. Letting go.

Context is important. Context can change everything, even the simplest of statements like 'I love you.' Emotional story about Rick's feelings and reactions to the shooting, and a different kind of potential roadblock to their relationship. NOW COMPLETE.

Castle has a plan for Kate's birthday, but then it eventually morphs into a sub-plan to pull a fast one on Lanie and the guys. Caskett moments in this one. Total AU. *Complete*

When Kate Beckett went to get her book signed by Richard Castle, she never imagined that she'd end up meeting his daughter, much less offering to babysit for the afternoon. AU.

They've both said it is. Is it really? Are they fooling themselves? Or do either of them really believe the lie?

Castle/Beckett, "To Kate" universe. It's strange to hear her best friend talking this way, and Lanie realises it sounds strangely like she's talking about forever.

Castle wasn't going to challenge Beckett's statement that this was déjà vu. In the end she'd realise it was fate. Set after 3.17

Castle/Beckett. The first time Alexis finds them, she knows she wasn't supposed to find them at all.

A late-night motorcycle ride and a heart-to-heart talk. Sort of a sequel to "Hit and Run" albeit with much less humor and much more drama. Early Season 4.

The call about the body came from Lanie, at four in the morning, on her day off. Lanie never called her about bodies.

Rick Castle, who kept her from freezing to death and held her hand in front of a bomb, prepared to die with her, wasn't who she was going home with. Kate's night after the end of Countdown.

When Beckett steps away from her desk Castle's curiosity gets the better of him. He never expected to be crushed by what he found in her drawer. Is it too late for them or can he convince her that he's her 'one and done? Rated M, not fluff, angst warning.

Kate Beckett doesn't do family gatherings. Then again, her aunt Lily's never died before.

What happens at The Old Haunt stays at The Old Haunt.

A continuation of Dangerous Game. Highly recommended that you read that first. Beckett tries to figure out where she wants things to go with Castle. Meanwhile, a serial killer fixates on Beckett.
