Set in the third season, episodes The Setup and The Countdown. 3x16 and 3x17.

Kate marries Josh but says Castle's name at the wedding. Based on the Friends Episodes 4x23 and 4x24 'The One With Ross's Wedding' and prompted from the Castle Fanfics prompt blog on Tumblr.

"She stares at Jacinda, yearns to be everything that the woman is, because she knows her lips taste like Castle's, knows her skin is painted with the scent of him. And maybe if she was blonde and flaky, fun and uncomplicated, Castle would want her just as much as he wants Jacinda." A three-shot fix it for the "47 Seconds"/"The Limey" arc.

Pyrolysis: the application of intense heat to burn off impurity. Or in this case, to cause impurity. One-shot fluff.

The Castle family has dinner. Bad summary, I know, but it's just a fluffy little story that my head made me write. And like always, I don't own Castle, I wish I did.

"Richard Castle just has to be up to something. Kate has known her husband long enough to realize when he's being sneaky and her husband is definitely up to no good. He's been spending lots of time with Max, talking to him in hushed tones. And Kate has no doubt in her mind what he's trying to do. He's trying teach their son new words." Fluffy Halloween Oneshot.

Lady Katherine Beckett's life is thrown into turmoil when her family is attacked, forcing her to find refuge with the crew of Captain Montgomery's pirate ship. The Captain takes in the young girl and raises him along with his crew of misfit youth and his young daughter, Lanie. Kate becomes his successor and helps Sir Richard Castle and his family. AU. Eventual Caskett. T for now.

AU On the fifth day, even before boarding the train, he had a moment. If he were to describe the moment, he'd say it was an infinitesimally small fracture in time.

"Cuando Castle sintió a su musa devolverle el beso como aquella fría noche en el callejón hacía más de un año, quiso llorar de alivio. Y con cada beso el regusto de traición se diluía en otro más puro, más fuerte. Uno que hacía que los corazones de ambos latieran frenéticos" One shot, Versión AU de la discusión de Always y regalo de cumpleaños a distancia ;)

It isn't an official rule, per se, but this morning it's not about her. It's his morning. The story of how Castle and Beckett make the most... effective use of their mornings.

Traducción de la historia "Teacher's Pet" de TrinityEverett. "Sin embargo, sus ojos van más allá del jefe de estudios para fijarse en el hombre que lleva pegado a sus talones. Ella conoce a ese hombre. La cara de ese hombre está impresa en la tapa del libro que tiene entre las manos ahora mismo. Pero, ¿qué está haciendo Richard Castle en su clase de Lengua?"

This was a prompt from mysafewordisapples. Castle is murdered and comes back as a dog, but has 2 weeks to help Kate find his murderer. If he does he comes back as a human. If not he remains a dog. Tell me what you think. This is one big chapter! So yes, there is Character Death. Just how permanent, you get to read to find out. - COMPLETE

Just a random AU one-shot that came into my head

What happened after Rick left Kate at the end of season 3's 'One Life To Lose'. This is the Epilogue, because everyone wanted to know what happened at the end of chapter 3.

AU meeting Who would want to rob a book store? And take hostages? Detective Beckett has see it for herself... because Richard Castle is there too

AU story of mine that takes place after the epic proposal in Watershed. Kate Beckett's life is changing in more that she thought it would. Castle's proposal and a surprise visit from someone from her past will make the future uncertain, but exciting. Note: Story contains an OC. Bumping rating to M as of chapter 3 for language & violence. (Don't know if there will be smut yet...)

Traducción de una historia de Tumblr, de Bravevulnerability. Ambientada después del final del 3x17."Castle no puede esconder su sorpresa cuando abre la puerta y la encuentra de pie al otro lado, sepultada bajo varias capas de ropa, pero aun así sintiéndose desnuda y expuesta al frío del invierno."

2x18 AU. After Beckett lives, Dunn decides he has to kill again, going after one of the few people who were truly important to her even if she denies it. Castle.

Life is full of unexpected twists and turns, so while Rick and Kate attend Ryan's wedding, their paths meet at a crossroads that will force them to decide on taking the same journey or going their separate ways.

Castle and Beckett return to the shooting range for some practice. Insert for 7x17, Hong Kong Hustle.

Prompt from CastleFanFicPrompts on Tumblr: Post-47 seconds: after the talk with Martha in that public place, they go to the loft and Castle can finally letting out his anger and feelings to Martha about Kate's lie. While he's talking he has an heart-attack. (No death, please). Martha-Kate moment and Caskett moment too. One Shot.

AU Rick and Kate meet in college and end up having Alexis. This is just how I think it would be. I just did some editing that might make it easier to read. So enjoy! PICTURES ARE ON MY PROFILE!

It's not the same Richard Castle who got her pregnant. The one who was rescued is distant, doesn't touch her and hasn't felt their child move. It is decision time. S7 AU. Tumblr prompt

Before marrying a best-selling author, before becoming the star detective of the Twelfth Precinct, before 3XK even earned his name, there was a young cop by the name of Kate Beckett with a burning drive to solve the case that destroyed her family: her mother's murder. But this event is the only thing—besides Richard Castle—that could cause her to question everything. Two-shot.
