Rick Castle and Kate Beckett had planned on going to Stanford together ever since the beginning of senior year, but when Rick's mom Martha suddenly had an amazing acting opportunity in the UK, Rick had to abandon ship and leave Kate to go to Stanford alone. Rick promised Kate that he would be back for Kate's college graduation, but when Kate finally graduated, Rick never showed. But Rick never knew before he left Kate he left her with one thing that reminds Kate of him everyday- a baby girl. Ten years later Kate is working for the NYPD, still single and Rick is a famous author in the UK, married twice with a daughter named Alexis. He decided to move back to the US for eight year old Alexis to get to know her country. Coincidentally he bumped into Kate, but Kate refuses to let him in because of the vain promise he made years ago. Will Rick find his way back to Kate? Or will he just be the boy who never kept his promise? Castle AU fic, enjoy!

Kate Beckett is a homeless woman in her twenties and one day a man stumbles across her. Richard Castle can't stop trying to convince Kate to stay with him, but Kate doesn't want him in danger. She doesn't want him to be in the same danger as her, and she tries her best to be cold but nothing seems to drive him away. She even meets his 5 year old daughter and his mother and they are being nicer to her than anyone has been since her mother's death. She really doesn't want to leave them but she can't risk them being in danger. The question is, will she follow her mind... or her heart? Disclaimer, I do NOT own the characters!! All rights served to the amazing story writers behind ABC Castle!

Kate Beckett and Richard Castle are two spies from different organisations and their jobs are pretty much to kill people who their bosses tells them to get rid off. So when they get each others names it's not a big deal other than they just got home from big assignments and they both needs to chill. Lanie and Jenny takes Kate out to a club and to the same club comes Rick and his buddies, Javi and Kevin. Without knowing who the other person really are Kate and Rick bumps into together and that's when life interferes and makes it a hell of a lot harder to fulfill the mission.
