What if life as you know it wasn't what you thought it was? What if you found out the truth? And what if people you loved could never find out? Someone is about to find out that it is a lot more complicated than anyone thought. Plus remember just one thing. THERE CAN BE ONLY ONE! JUST THE ONE! Knowledge is power but it can also be a curse if you let it. -NOW COMPLETE

This is an AU story starting during the finale of season six. It explores the history that Castle had working with the CIA and how he is pulled in again, along with Kate. This is not a secret agent story just using the Castle name. He and Kate are very much Caskett, and they did manage to get married. Cover art by @Artifex Prime.

"I don't want you to go." "I'm sorry, but you don't have a choice." Caskett AU with a touch of sci-fi

A Caskett Short Story. Post-series. Sometimes it takes a tragedy to change a life. Will Kate and Richard Castle be able to mend what they had? Or will they continue to hide behind coiled smiles?

"She should have gotten drunk and crawled into his lap ages ago. What had she been thinking? She would just have to make up for it now." A smutty AU post-ep for "The Limey."

Story for Caffinate-me's #BookstoreAU challenge. Castle and Beckett meet in the worst way possible at the worst time possible, but their initial antipathy develops into something else.

Castle planned to have dinner with the boys but someone special shows up in their place...

Kate Beckett seeks advice from some luminaries. Caskett, oneshot.

She feels her body scream as she leaves. Pulling away from Castle when he was so overwhelming close like that took every last ounce of her strength now all she's left with is just enough cognitive ability to understand that she needs to make it to her car. Beyond that, is anyone's guess. A case affects Kate a lot more than she expects, will she be strong enough to lean on Castle?

He always ordered chocolate, but tonight he got strawberry. A one shot.

Just a little story about how I imagine the Castle family celebrates Kate's birthday

"I bet you don't even know there are different levels to your jealousy. Sometimes it's sexy, but tonight it's just downright adorable." A little fluffy Caskett one shot with the whole package. A what should have been their future. Banter, jealousy, family and more!

Rick and Kate are married and have a daughter named Alexis. They known it each since there parents knows each another. One day on January 9,1999 Rick almost gets killed again. His father and Kate's Mother died. Completely destroying their family. Since Rick got a mission he's been gone for 2 years and come home again for a case that happen 10/12 years ago. AU (Up for Adoption)

A whole difference take of Rick and Kate. Rick and Kate known each other since they where babies. Rick's has two younger sisters, Meredith and Jordan. Johanna Never Died. Completely AU. (This Story is up for Adoption. P.M. me if you want this story)

Beckett returns to the precinct to find that things have changed more than expected. Set early in Season 4.

"What would you do if it was the last night of your life?" He knew what he would do. He'd do what he hadn't done before the bomb, what for long, desperate, gruelling and agonised moments he'd thought he would never have the chance to do. Two shot. First chapter T. Second chapter M.

Just a moment between Caskett

Inspired by the prompt: "Beckett gets to know Castle while he's married to Gina." Pre series AU.

Se la 8x08 fosse finita diversamente...

She has Castle to thank for her life and a roof over her head, she can plan a birthday party for him. - Caskett, Season 2 AU.

Sophia Turner had been a traitor until the end. She'd played Rick Castle and he never knew it. She'd come away with the only thing that can come back and haunt him, or possibly kill him. Will Kate save him in time or has he gone past the point of no return? Even in death she still finds a way to wound him. Kate B., Rick C., Alexis C., Martin D., Sophia T., Martha R. & OC

When Richard Castle meets Kate Beckett four months after she was shot at her captain's funeral, he's catapulted into a decades-long conspiracy that has long haunted her. Working by her side and helping to solve the case may be the only way he can give her the closure she needs. A very AU take on the end of the JB case.

This is absolutely crazy. It could never work - despite Alexis' and Mayor Weldon's assurances, Rick Castle could not lead a group of seven million New Yorkers into the new millennium. Or could he? He loves New York, the people, the aura, the past and the potential. But will his family survive the onslaught into his life? Still, that's not his biggest hurdle.

Finally back home with his family, Rome, Castle's 10 year old son struggles to put the events of his kidnapping behind him. With the help of those closest to him, he is slowly returning to his old self as Castle's creative, mischievous, and smart alec mini me. Follows directly along with season 2. Third in 'Like Father Like Son' series. Chap 29 finally up.

A round robin story, set post Boom, where nothing is as it seems and almost nothing goes as planned...
