Disclaimer: I do not own Big Time Rush or anything pertaining to the show or band. Jace is my oc. This is my first BTR fanfic so go easy on me but feel free to give me some good feedback on how I can improve and make it better or just stuff you'd like to see happen in the plot.

Chapter 1: Big Time Summer

Attention passengers, we are currently descending the Los Angeles area. Please secure on your seatbelts and remained seated as we begin our decent.

Jace Diamond put away her copy of Pride and Prejudice and pulled the ear buds out of her ears. She had been listening to her brother's band, Big Time Rush. James had left Minnesota 6 months ago to be in a band with her friends Kendall, Carlos and Logan. The band had become a success and now there were already working on a second album. Since schools had just let out for the summer and her mother had suggested she visit James in L.A. She thought it would be a great summer trip before her senior year of high school. Now Jace was on a plane to L.A. to surprise her brother.

A long line of cabs waited outside the airport when she got out. After giving the address to Rocque Records, Jace pulled out her phone and sent her mom and quick text that she made to it L.A. and was heading over to see James.

"Hi, is it possible for me to go in and see Big Time Rush," she asked the office receptionist. "I'm James Diamond's sister."

"Can you verify you're his sister," she asked politely. "I'm afraid we can't let anyone in without a pass or I.D."

"Yeah, here you go," said Jace, showing her driver's license.

"Thank you, go on ahead, it's the last door on your right," said the receptionist.

Jace walked into the studio to see her brother's producer Gustavo Rocque screaming. "Dogs, someone please tell me what is wrong with Kendall! Now!"

"It's Jo," she heard her brother answer through the recording booth; "He's been like this ever since she left for New Zealand."

"Fix him," Gustavo shouted.

"We've been trying," Carlos answered.

"Ummm, excuse me," Jace interrupted.

"Who are you," Gustavo glared.

"Be nice," a pretty dark skinned woman hissed.

"Kelly, I can't have any interruptions. We need to get this single out or Griffin will have all of our hides."

"I'm Jace, James's sister," she answered.

"And I care why," said Gustavo.

"Jace," James smiled, rushing out of the recording booth. "What are you doing in L.A." he asked, spinning her around.

"Mom said it was okay for me to visit you so I thought I'd make it a surprise," she said smiling.

"Well I'm glad you're here," said James. "Come on, the guys are going to want to see you," he said, pulling her into the sound booth.

"Guys, look who's here," exclaimed James.

Logan and Carlos rushed over to engulf her in hugs. She had know the three other members of Big Time Rush just as long as her brother and they were her friends, even if she younger than them and a girl. They would always let her tag along to play. She even let them teach her how to skate and play hockey when she was twelve.

Jace eyes fell on Kendall, laying face first on the couch in their little booth. "What's up with K-dog?"

At the sound of his name, Kendall turned his head to face her and said, "Nothing is wrong with me."

"Yeah right," said James.

"Does really look like nothing's wrong bro," added Carlos.

"The non-smiling and mopping around everything might have something to do with that," Logan told him.

"Forget Kendall for now," James interrupted. "I'm so glad you're here."

"Thanks," she said smiling.

"Alright, now that the happy family reunions are over can we get back to the new single that has to be done by tomorrow," shouted Gustavo.

"Or we could take Jace to the Palm Woods," shouted Carlos. The rest of the boys shouted in joy and bolted out the door, grabbing Jace and Kendall.

"Jace, I'm so glad you're here," Kendall's sister Katie exclaimed when she spotted the teenager.

"Glad to see you too kiddo," laughed Jace.

"I already had a spare bed put in Katie's room when you're mom called," said Mrs. Knight. "It's going to be great having another girl in house full of boys."

"You mean hockey heads mom," said Katie.

"Thanks Mrs. Knight," Jace said, giving the woman a hug.

"Why don't you get unpacked and I'll make you some snacks," said Mrs. Knight.

"I'll help you," shouted Katie, pulling her down the hall.

"So where's there to do here," asked Jace.

"Lots of stuff," said Katie, jumping up on to her bed. "There's the beach, there's a movie theater pretty close, the pool downstairs in awesome and the park here is pretty fun too."

"Sounds like we'll have a lot to do while I'm here," Jace said.

"Yup, it's going to be great," Katie smiled.

"Hey Katie, can I ask you something," asked Jace.

"Yeah sure," answered the ten year old.

"What's up with your brother? I've never seen him so down," said Jace.

"He was dating this girl for year and she got a move deal in New Zealand. So now they're broken up," explained Katie.

"Poor Kendall," Jace frowned.

"Hey Jace, wanna go down to the pool," James asked, coming in with the rest of the boys.

"Yeah sure," said his little sister, "but where's Kendall?"

"His room," said Logan. "He really doesn't want to hang much lately."

"Well I haven't seen you guys in months and I came out from Minnesota just for the summer," said Jace. "You guys head down. I'll get Kendall."

Jace knocked softly on Kendall's door. "Go away guys," he shouted through the walls.

"It's not the guys," she said coming in. "So will you at least talk to me?"

"Hey," Kendall said in surprise. He sat up and patted the space next to him on the bed.

"You alright," she asked sitting next to him.

"I'm sorry I didn't give you a better welcome. Alot's been going on," he told her.

"I heard," she nodded, pulling him into a hug. "If it helps, I can say I know the feeling,"

"What do you mean," asked Kendall.

"A really liked this one guy and one day he just up and moved," said Jace.

"Wait, you had a crush? Who," he asked.

"Forget it," she said, playing it off like it wasn't really important. "We went to the same school but he was older. He never really noticed me anyway."

"He missed out," he told her.

"Thanks but the point to my whole story is that it gets better. Yeah it's a slow process but that's how every wound is. It takes time to heal. You'll see Kendall, one day all the pain will be gone," she told him getting up. "We're going down to the pool if you feel up to it.

"Jace," Kendall called after her.

"Yeah," she turned around.

"Is the pain gone…for you," he asked.

"No, not yet," she answered with a half=heartened smile.

James, Carlos, and Logan had already left for the pool so Jace made quick work of changing into her swimsuit and slipping over a pair of denim shorts and a t-shirt.

"Told you he wouldn't come," shouted James from the pool when he noticed his sister walking towards them alone. At that comment, Carlos dunked James head into the water.

"My hair," Jace heard her brother shout in terror. She couldn't help but laugh.

"Aren't you coming in," Logan asked when he noticed her claim one of the beach chairs and pull out a book.

"I will. I just want to relax for a bit," she told him.

Jace tried to read but the noises around her were too unfamiliar and therefore distracting. She riffled through her beach bag until she found what she was looking for; her Ipod. She put on the ear buds and scrolled down her songs until she found Worldwide by the guys. As the words rang through her eyes she realized this was Kendall's song. It was his breakup and heartache. She couldn't stand listening to the song knowing how miserable Kendall must have felt singing it. She put her Ipod and book awhile; deciding to play volleyball with the boys in the pool.

"I got it," shouted Carlos, as he swan forward for the ball. James spiked it and it ended up hitting Carlos in his face.

"Sorry bro," James laughed. Even Jace was having trouble keeping her giggles silent.

"How about some smoothies guys," asked Logan.

"I'll take one," shouted James.

"One for me too," added Carlos.

"I'll help him carry them all," laughed Jace.

She and Logan got out and dried themselves off before heading over to buy smoothies.

"It's great having you here," Logan told her. "We've been missing home so much, with you here it feels like we never left."

"Thanks Logan, that means a lot," she said, leaning in and giving him a kiss on the cheek.

"What's going on," a voice called out.

They turned around to see a pretty brown haired girl walking towards them.

"C-camille," Logan stuttered nervously.

"Logan, who is she," Camille asked, pointing to Jace.

"T-this is…this is…"he stuttered nervously.

"Oh you're Camille," Jace shouted all at once. "I knew you're name was familiar. All Logan ever writes about in his e-mails is you."

"Really," Camille asked surprised.

"Yeah," laughed Jace. "I'm Jace, James's sister. Nice to finally meet you."

"Same here," said Camille.

"I totally forgot to ask you about your girlfriend," Jace said, turning to Logan. "I have so many embarrassing stories to tell Camille."

"Okay, those I need to hear," laughed Camille.

"Oh no you don't," Logan cut in, pulling Jace back.

"How cute," laughed Jace. "He's actually blushing.

"I got to head to an audition but how about we hang out later," asked Camille.

"Sure, that would be great," said Jace.

Kendall was still in his room when they headed back to 2J. Kendall's mother was in the kitchen cooking and Katie was setting the table.

"Dinner's almost ready. Honey could you please get Kendall," she asked Jace.

"Sure thing," she told her.

"Kendall," Jace called out, knocking on his door. She didn't get a reply so she opened the door and went in; finding out why she didn't get a reply. Kendall was fast asleep in his bed.

"Kendall," she said, trying to wake him up. The boy didn't move. He was asleep on his back with one arm across his face, coving his eyes and the other on his stomach. "Kendall," she tried again, this time giving his shoulder a light shake.

He stirred in his sleep but instead of waking up, Kendall pulled Jace in by her waist and cuddled closer to her.

"Uh, Kendall," she said, shaking him. "Kendall."

"Waa," he asked in his sleep.

"Wake up," she hissed.

"What's going on," a voice called from the doorway.
