One shot. Standalone. AU. Set in 2011 and the Season 4 timeline but Castle and Beckett never met when the Tisdale Case was active.

What happened after Castle and Beckett's date night in the Hamptons. A smutty one-shot insert to "What the Heart Wants" but it can stand alone.

Come an enjoy an imaginary Season 9, Episode 1 of Castle

Beckett's birthday isn't just a special day, it's the beginning of a new adventure. A Post-Series story.

The title says it all. Our favorite duo find themselves on a planet that no one would want to intentionally visit. Can they survive?

Castle has enough when Beckett compares him to Dr. Motorcycle Boy. NOT FOR BECKETT LOVERS.

"A small blue dot in her vision. But it was the wrong blue. It wasn't her blue. She wanted her blue. But it wasn't there." Fluff in three chapters.

Part 3 of the PRIVATE EYES series. They know his name. He knows theirs. Now Detective Kate Beckett and her boyfriend, CIA Agent Rick Castle, must work together to bring down the man responsible for her mother's death. Meanwhile, Ray Kilmer (aka Cole Maddox) seeks revenge on his former employers. AU. Spy Castle. Castle Ficathon 2019. NOW COMPLETE.

America is under attack. A deadly foe unleashes weapons of mass destruction and masses of fanatical terrorists. When the enemy stages an attack in the city of Tampa as a dress rehearsal they encounter an unsuspected obstacle: FBI counterterrorism agent Kate Beckett and an ex-marine turned college physics professor - Richard Castle.

A head wound and years of trauma. Post-ep for 6x22 "Veritas"

When Detective Rick Rodgers moved back to New York from LA to take a job at the NYPD's 12th Precinct, the one thing he expected less than being haunted by his predecessor's cases, was to be living with her ghost. AU

With their Christmas in England around the corner, Castle and Beckett return to work with the Hamptons PD when a man is discovered dead outside a burning cabin. They find connections to local schools and Egyptology in their race to find the killer before more end up dead. Thirty-third in the Beware Of Darkness series. Caskett pairing. Complete

Authors Note: Another What If based on the episode, A Deadly Game (TY Cyotepup4 for the correction). Starts off with Canon dialog, quickly goes completely AU. No Gina in the Hamptons, just twists of fate in the Castle's lives.

"For the first time in weeks, something feels normal and right in her life. This is exactly where she needs to be, standing with her shoulder bumping his, her body humming simply from being near him." What if Castle and Beckett had made their anniversary dinner in 8x07?

Another variation on my "Bear an I" Story. "Life here began way out there amongst the stars." - NOW COMPLETE

Caskett are in the middle of something. Perfect timing for Ryan to interrupt. What will Caskett do? (set sometime after 5x18 The Wild Rover)

Authors Note: Based on Canon episode Probable Cause with some interesting twists, also a prompt from our fan Retired1984 will be addressed as well, the prompt will appear at the end of Chapter One.

"As much as she loves Halloween with their kids, she wasn't too upset at having a night off with her husband and the loft all to themselves." A post-series one-shot.

Totally AU where Beckett has a younger sister. Rated T for language that is sure to come later.

OS. Il n'y a rien de plus tendres que les instants partagés par les amants dans l'intimité de leurs draps... et il faut bien que Javier en profite, puisqu'il sait que tout pourrait bien s'arrêter d'un claquement de doigt. Pas dans le sang, pas dans la violence de leur métier, mais dans un son de cloches. / ! \ Slash, Rysposito, relations sexuelles / ! \ Happy end. Enjoy !

Castle has a different secret than Andrew Marlowe intended. Story posted for Castleficpromoter's Halloween Bash 2019

Un petit OS d'Halloween qui arrive avec un jour de retard, et je m'en excuse. C'est tout simple, et un peu... coquin. J'espère que ça vous plaira.

It's a few days before Halloween and Jake and Reece Castle are getting into mischief. Story based on Random Ship E's adorable baby Batman and Joker picture. Written for the 2019 #CastleHalloweenBash
