Down the Rabbit Hole

Summary: The boys of Big Time Rush have it all – family, friends, love, fame and a huge paycheck waiting for them in the bank. Until one day, that is. Their world comes crashing down as they fall through the rabbit hole in a world they never imagined possible. With help from some new found friends, the boys have to stay alive and save the world while they're at it. Easy peasy, right?

A/N: There is KOGAN slash – already established (my ultimate OTP) so if you're uncomfortable, don't read it. Just a one-shot for now, unless I get positive responses then I'll make it a multi-chap (I do have some ideas already.)

Chapter 1: Meet Percy Jackson.

Logan plopped down unceremoniously on a pool chair, sprawling out lazily. His eyes slowly drifted shut as the scorching LA sun shone down on the pale boy. The smell of palm trees invaded his senses and Logan eagerly breathed it in, ahhh, there're nowhere like home. Big Time Rush had just returned to the Palmwoods after their first headlining tour. Sure, Logan loved to sing and he absolutely loved the thrill of performing on stage. But, between hours upon hours of gruelling dance practices, exhausting harmony breaks, and Gustavo's yelling, there's only so much he could take. Yup, Logan was just glad to have some peace and quiet. Not that it lasted for long anyway. Sounds of bickering soon drifted into his ears, making the poor boy very annoyed.

"She will be mine!"

"No, she will be mine!"

"No, she's mine!"

"Mine!"

James and Carlos were shoving each other right by the pool, arguing about god knows what. Logan aimed a particularly murderous glare at the two oblivious boys, formulating ways to shut them up in the most violent way possible. Suffocation, too risky and high chances of getting caught. Drowning's possible, Logan thought, eyeing the pool. Hmmm, how about pushing them into - He was cut off when his eyes were met with a tanned, muscular chest. Logan looked up, angrily at first, into green eyes and a familiar smirk. His anger dissolved instantly, pushing himself off the chair to meet Kendall's lips. Logan let himself melt into his boyfriend's arms, loving the fact that he could always calm him down. When they parted, Kendall quirked up an eyebrow, "So, what made you so angry earlier?" At his reminder, the pale boy's anger returned with a vengeance. Instead of replying, he stalked over to James and Carlos – who were still arguing oh god, and pushed them forcefully into the water.

James broke the surface, spluttering indignantly. "What was that for?" he screeched at the satisfied Logan and a highly amused Kendall, who had walked over and looped his hands around Logan's waist, resting his head on his shoulder. Carlos, on the other hand, was not at all upset, already engaged in a water fight with Tyler. Ignoring James' screams about his ruined hair (Logan had lots of practice with Gustavo), he inter-wined his hand with Kendall's, following the blonde as he made his way to the lobby. Logan padded behind silently, secretly admiring the contours of Kendall's back – which he smashed into soon after. Kendall had stopped short. "Ouchies," Logan rubbed his nose, leaning over Kendall's shoulder to see what happened, "is that Gustavo? Smiling? And acting like a human being?" Logan was beyond shocked; he has never seen Gustavo actually smiling, like absolutely never. Just at that point in time, Gustavo caught sight of the two frozen in place. He smiled at them and called out, "Get over here guys!" Logan was absolutely gobsmacked. Not only had Gustavo smiled – at them, he also called them "guys" instead of the usual "dogs" or recently, "idiot rush". A quick look at Kendall's dropped jaw answered his question.

Gustavo soon grew exasperated with the lack of response, starting to yell loudly with a raised fist. Ah, here's the Gustavo we know and love, Logan thought wryly while Kendall led them over, having broken out of his shock. "Well, where's the other two idiots? I need to introduce my dogs to my, uh," he trailed off. "Family." A feminine voice supplied the answer. Logan took a triple take. Gustavo had family?! He was too focused on Gustavo to realise there were 2 strangers standing next to Gustavo. A blonde girl stood off to the side, having been the one answering. She looked straight at Logan, a shiver going through his body as her calculative grey eyes studied him closely. Still, Logan couldn't shake off the feeling he knew her somehow. He stared back at the blonde thoughtfully, until her gaze turned stormy, like mini tornadoes swirling, forcing Logan to break off eye contact. Logan gulped and turned to the other stranger. He was tall and built, like a swimmer. A mop of black hair and piercing green eyes met Logan as he gazed curiously at him. What is with these people and their seriously scary stares? Logan burrowed himself closer to Kendall, whose arm tightened around his shoulder securely. However, despite the aura of terror, there was no denying that both people were gorgeous. Not your run-of-the-mill Hollywood hopefuls, but almost too beautiful to be human.

'Hi I'm Kendall, and this is Logan. We're one half of Big Time Rush." Kendall flashed a lop-sided grin at the two. Logan looked up appreciatively at his boyfriend, who always seemed to know how to defuse tension. The blonde girl stepped forward and introduced herself as Annabeth Chase, pulling forward the green-eyed male with her.

"Hi, I'm Percy Jackson."
