Set after the Voyage of the Dawn Trader and mostly based off the films but the locations etc. are from the novels! Read and Review and let me know if i should continue :)

It's been a year since Lucy and Edmund Pevensie returned to Narnia. Aslan told them it would be their last time there, but both Pevensie children hoped that they would be able to visit Narnia at least one more time. Little did they know, that was just about to happen.

"Edmund! Come on! The bus is about to leave!" Lucy Pevensie desperately called for her brother who was taking too long in the small bookstore near their private school. Edmund hasn't been the same since they came back from Narnia, he's back to his much bitter mood he had when they were younger. The idea of being able to return to Narnia was the only thing Edmund looked forward to, and with that being gone he was in a foul mood most of the time.

Lucy sighed as she saw Edmund slowly come out of the bookstore carrying a huge stack of books, Edmund began to read a lot, trying to distract himself from what was going on in their lives. He started seeing this girl, Amelia whom Lucy thought was the most annoying girl she's ever met. Edmund didn't seem to enjoy her company as well, which made Lucy think he kept her around out of boredom.

Susan and Peter were both in America with their parents while Edmund and Lucy were back in England. Both of the younger Pevensie siblings were upset that their parents didn't bring them along with them, but Edmund was more vocal about it than Lucy was. "Finally, we're going to be late for class!"

"Would we even miss anything interesting." Edmund rolled his eyes as he entered the bus after Lucy. School felt useless to Edmund, he'd experienced way more than any normal person has and gained all the life experiences he could back in Narnia. That's what he kept telling Lucy but she always reminded him that they're lives are in England and not Narnia. "Edmund, it's been a year and we're not going back. You just have to accept it...I miss it too, you know." Lucy sighed as she watched her brother scoff. She knew it was hard for him, he wanted to fight in the war like Peter, but he was still too young and Edmund always thought he wasn't doing anything that would make a difference in this world, unlike in Narnia where he was a king.

Suddenly, Lucy felt a rush of cold air on her face, which was strange because they were inside the bus. "Edmund...did you feel that?"

"Yeah...strange isn't it?" the siblings began to notice that everyone around them froze and the their surroundings outside the bus were changing as well. "What's going on?" Lucy whispered, "Do you think we're...we're going to—" Before Edmund could finish his sentence, the bus began the tear apart and the people disappeared, and they were standing in the middle of Cair Paravel.

"Edmund...we're in..."

"Narnia." Edmund finished as both of them stared in awe. Lucy began to run around laughing while Edmund stood there in shock. "Did you ever think we were going to come back?" Edmund yelled, "No... I thought the last time was the last... I'm not complaining though!"

The door sprang open, and out came Caspian striding excitedly towards them. "Caspian!" Lucy exclaimed and ran towards him, Caspian picked her up and spun her around. "I've missed you so much." Caspian whispered in her ear. After letting Lucy down, Caspian and Edmund hugged but were speechless, they thought they'd never see each other again.

"How is it possible that we've come back? I thought we'd never see each other again.." Lucy whispered, "I asked Aslan for a favor...I need your help." Caspian's face suddenly dropped, so did Lucy and Edmund's. For Caspian to ask Aslan for a favor, he must be in dire need of help. "Anything, you're like our brother." Edmund placed his hand on Caspian's shoulder. "Thank you, let's go up to the library and discuss things."

They were all seated around the table in the gigantic library of Cair Paravel and Caspian was pacing around restlessly. "Caspian, what is it?" Lucy asked, her and Edmund were both worried because they haven't seen Caspian this nervous since their mission on the Dawn Treader. "I'm so sorry to ask for your help—"

"Why are you sorry? We'd do anything to help Narnia!" Edmund stated, "It's not to help Narnia...more of ...helping me..." Caspian finally stopped pacing, "Are you alright?" Lucy piped up, "Yes I am...there's something you both need to know." Edmund and Lucy both stared at him curiously. "I have...a sister." The Pevensie siblings didn't know what to say, they thought they knew almost everything about Caspian and thought that he would have at least mentioned his sister if he didn't want them to meet her. "A sister." Lucy repeated, "Yes.., her name is Isabel."

"So, did you bring us back to meet her?" Edmund asked, Caspian paused for a moment and sighed, "No, I asked Aslan to bring you back in order to get her back." Lucy and Edmund both motioned for him to continue.

"What happened to her?" Lucy whispered, "My uncle did. After my father passed, he sent her away to be betrothed to the prince of Calormen when she was twelve. He wanted me to feel alone and miserable so I would feel too weak to try to take the crown if ever he bore a son, which he did, and we all know how that turned out."

"Isn't the prince of Calormen known to be cruel?" Lucy asked, "Yes, and with the death of his father, he will soon become king, and when he and my sister are married, there's no chance of getting her back."

"So, what do you want us to do?" Edmund could tell Caspian was desperate, and if the roles were in reverse, Caspian would do anything to help them as well. "Well, I obviously can't be the one to do it, since my intentions will be obvious, but, If you and Lucy pretend to visit Calormen for diplomatic purposes, as you are still seen as an image of the rulers in Narnia, and pretend to make deal on the shared land that we have, the prince will have to invite you to stay as a form of diplomacy."

"And then what do we do?"

"You must take my sister and leave." Edmund and Lucy looked at each other, they knew it would cause trouble among them and the people of Calormen. "Wouldn't that cause a war?"

"Yes, it would, but you don't understand...prince Joffrey is known to abuse and sometimes murder the women he's involved with. My sister is safe for now as he cannot touch her in an intimate way before marriage, but after... I gravely fear for her life. I'm still trying to think of what to do after she is taken from there, but, I have to get her out of there...will you help me?"

Edmund and Lucy were silent for a while, despite the possibility of another war in Narnia, there was no question what they had to do, "Of course we'll do it, your family is our family, Caspian, and you're like our brother." Lucy stood up and hugged him. "Thank you so much, you have no idea how much this means to me." Edmund stood up and walked over to Caspian.

"We'll get her back, I promise"
