Hey everyone! This is my second leviathan fanfic and it's a crossover of that vampire movie, "Let the right one in", or "Let me in". They're the same thing either way so it shouldn't have much difference although I might change some parts. Enjoy! Also, Alek is 16 in this story and same with Deryn. Although I don't really like deryn x alek, I thought that couple fits with this story so I put it in. You could send in your ocs if you like and I'll maybe put them somewhere in the story.

Prologue

Small village on the border of France and Spain. Fall of 1917.

" Run your highness! Hurry!"

Fear coursed through the boy driving his mind on the brink of breaking point, but his body disobeying him, kept on running. Gunshots can be heard all around, wails and screams of citizens who are running around the street trying to dodge from the bombs. Not all were actually running, some were on the ground moaning in pain from injuries while others just stayed…silent. He didn't wait to find out what happened to those silent ones. 'Why', he thought to himself, 'why is this happening? Why are they attacking innocent citizens when I'm their target?'

He felt like tearing himself to pieces and then hand himself over so all this madness can stop, but that would put everything his men and his father worked for to waste.

Another bomb exploded near him sending debris flying everywhere. The impact was so strong it flung him against a half destroyed building which unfortunately burned down in the first strike. Thinking that he might find some shelter from the stormwalkers, he went him the building thinking it might be safe.

"God, it's so dark in here. " He mumbled quietly to himself and walked further into the building. The darkness was infuriating and the building isn't suppose to be this dark, but thanks to the stupid stormwalkers, they knock it down and set the whole thing on fire which darkened everything as an aftermath. "Ah! I'm such a dummkopff! I can't believe that I forgot that I have a pocket flashlight!" His hand dug his pocket searching hopefully that the flashlight is actually there, and to his relief, not only did he find it, but it still worked!

He roamed further into the building hoping to find a back door somewhere, but the closer he got, the more the foul stench filled the air. " Mein Gott, what is the terrible smell?" He muttered to himself. He hoped that the faster he could get out of here the faster the smell would go away; his thoughts were short-lived when he tripped over something.

"Ow! What the heck?" he muttered rubbing his forehead, since he did a face plant on the ground. "What the heck did I trip on?" he thought to himself. Flashing the flashlight at the figure in front of him, he dropped it almost immediately after the horror bestowed onto him. " Oh my god.." In front of him was a body. Not just any, a corpse that is half-burned revealing flesh that is slowly decomposing. He turned around and behind him was the charred body he tripped over. Gripping his flashlight, he shone the light around him and saw that the whole place was stacked and filled with decomposing corpses; ranging from infants to elders. He shuffled backwards, but no matter where he goes, the bodies surround him. Suddenly he felt a hand on his shoulders; he almost let out a scream before a familiar voice whispered into his ears.

"Your Highness! It's me, Hoffman!" Hoffman gripped onto the boy's shoulder and led him slowly to the door. "You have to hurry your highness before they ca- TURN AROUND SLOWLY WITH YOUR HANDS UP!" Before they even know it, soldiers poured into the building and as he wasn't paying attention, Hoffman pushed him behind a broken table to hide.

"SIR, TURN AROUND AND ANSWER OUR QUESTION OR YOU'LL BE FINDING A BULLET IN YOUR HEAD BEFORE YOU CAN EVEN COUNT TO THREE." Shouted the leader of the group. The boy watched from his hiding spot as Hoffman turned round to face the soldiers. "Anything that you need sirs?" He asked calmly with his hands still behind his head.

"WE ARE CURRENTLEY SEARCHING FOR THE MISSING PRINCE. HAVE YOU SEEN HIM?" The leader asked once again and showed a picture of the boy itself. Hoffman hesitated before saying, "I'm sorry sirs, but I'm afraid not that I don't recognize him.

The soldiers lowered their guns but then brought it back up. "I'm sorry, but it seems that's not the answer we're looking for." The leader smirked and a second later, Hoffman fell to the floor covered in bullet holes. The boy stifled a scream when the blood sprayed all over him. Tears forced its way out of his eyes. "I've got to get out of here, or they're going to kill me!" he thought to himself, and without thinking, he dashed out of the door. Thankfully, the soldiers didn't hear him so death was relieved in that area. (for him) Although is luck was short-lived when he felt excruciating pain bloomed in his had just been shot. Just right after, he collapsed, soon a red puddle of blood formed around him. He slowly dragged himself across the street littered with corpses and propped himself against a wall. "Is this the end?" he asked himself. "Am I going to die here meaninglessly?"

Although he didn't expect an answer, a deep voice called out to him. "No, this is only just the beginning for you."

The boy looked up at the figure , but his vision was getting blurry since he can't hold on much longer. "Are you Lucifer?" the boy called out to him. "No," the figure replied back, "But you do not need to know."

"Why are you here?' mumbled the boy quietly and winced from the pain in his shoulders. "It's sad boy, you had a bright future ahead of you, but now, it's crumbling down right in front of your eyes. It's a shame that you're not going to live much longer; your life force is slipping away after all." The stranger said ignoring the boy's comment.

"If you're going to pity me, then leave me be." The boy snarled at him but as a result coughed up more blood. "But there is a way to let you live. Although you may have to live with the burden for the rest of your life." That just perked up the boy's attention to the figure and gazed at him with wondering eyes.

"I see, so you want to live don't you. Then I shall bestow the burden upon you." Before the boy d even react, the stranger pounced on him and sunk his razor sharp teeth into the boy's neck. At first, the boy felt numb but then the pain commenced. It felt like his body was burning up from the inside, the pain was so immense, he didn't even have enough strength to scream; but only lay there twitching on the ground.

The stranger lift itself up and looked down upon the boy and said, "The pain is normal, but after this you'll not be a weak mortal anymore." The stranger started to walk away before stopping and smirking. "You'll be able to grasp what you want…

….Isn't that right, Aleksander?"...

Lewes County Town, England

"…..Therefore, Emperor Franz Ferdinand, King Vincent of Wales and the ambassador of Serbia ariived at London yesterday. Both are staying for at least 3 months and each is audience to her Highness Elizab-

"Deryn Honey, would you please check if the messenger Lizard came yet?" Deryn's mother, Emma, called from the kitchen. " Check if there is any mail from the Huxen Company, if there is, could you put it on the counter?

"Fine…" Deryn called back. She turned off the TV as she made her way to the mailbox. The weather wasn't that cold so she didn't really need a coat although it was winter. "Ad, Junk, Ad, coupon, and oh! Here's the letter Mom!" she threw the letter onto the counter and walked towards her room. She stopped when she saw the TV, but then again, there was nothing good on except boring old news, so she just stalked off to her room. The door creaked open when she walked which reminded her that she seriously needs to oil the hinges, she then collapsed onto her bed and looked out the window.

Snow started to drift down onto her window pane which was clearly nothing out of the ordinary. That was just so like her, she doesn't like ordinary. Her mom wants her to be stuck in dresses and act like a proper lady, but that is clearly not her wish. To rebel, she cut of her long hair which she actually preferably liked and she wore boyish clothes instead of frilly girly clothing's. Although she doesn't attend any sports clubs, she still likes to fly around on the Huxley at his dad's place which is 3 km from where she lives now. Her way of life also makes her a bully target among some girls and guys, but she actually don't mind very much often, but sometimes when things get too frustrating because of them, she goes out at night to a playground and repeatedly slash a tree there until she calms down. (The reason she does that is because she always pictures the tree as those bullies)

Sighing, she made her way to her dresser and started to change into her pyjamas. Half-way on pulling on her pyjama pants, something caught her attention. A black Buick car (an expensive one at that) came up from the road and parked into the next door empty house drive way. The driver who was a man about 40 with a moustache and a stern look came out and then proceeded to open the door of the passenger seats. A boy, about Deryn's age came out who looks clearly nothing like the man. She couldn't really see the boys face, but she could make out that he has auburn reddish hair, he is wearing what looked like a designer brand coat and navy jeans which probably also cost as much as the coat. From looking, she probably guess it's a bunch of rich freaks, but why would someone as rich as them move to a small town like this?

The boy looks like he tries to help the man but the man refuses and ushers the boy to go inside the house. Deryn, being herself who looks for abnormal things watched them until finally the man disappeared into the house along with the boy.

"Why the bloody hell did I just waste my time watching some stupid rich freaks" she muttered to herself. "Ugh, I feel like I'm becoming a stalker like this watching every new person this way." She crawled into bed and then turned off the lamp. She stared into darkness still wondering about the boy, for some strange reason she can't stop thinking about him.

Little did she know that her future right there and then changed…. Forever.

Lewes High school

School again was once again, boring. Thinking that an officer coming by today was a bit of excitement , but noooooo, was she ever wrong. The officer was completely stupid and really did not see the real picture of the world. He even called her a silly little girl, and if the teacher hadn't been there that time, she would completely punch his lights out to next Monday!

Thank god school, was over soon, or she is going to seriously going to los ether sanity form the sheer torture of boredom. Just as she was about to grab her bag and leave, she heard a high shrilly voice calling her name. "OOOhh Deeerrryynnnn!"~

"Great, " she thought to herself, " Prissy queen and her dogs are here… again." Quickly grabbing her coat, she walked down the hallway ignoring the prissy and headed towards the door before one of her lackeys, a fat boy this time, blocked her way. "Yo Bumrag, I need to leave so could you move your hairy mutant body?" I sneered at him which made his face turn red as those red lobsters. Except uglier. The fat guy was about to swing a punch at her when Prissy cough* Sylvia came between them.

"Now we don't want any fighting do we?" she said in mock sweetness. Then she turned back to me and smirked. "Next time, why don't you keep your stupid questions to yourself? She really shouldn't question high-grade people like that. Your ugliness might rub off."

Irritated, I gave her the birdie which twisted her mock smile into a frown. "You are as dimwitted as you seem don't you Dirt-yn. Remember, my daddy is a first class Darwin scientist who is close to government officials that could get you in trouble!" I was going to rip her face right off when the teacher came around the corner. She looked at me straight into eyes and laughed, then walked off with her dogs.

She is in-sufferable! But, there's not much I could do about it, so in the end, I just walked home as I always do.

…

…

That night at home…

" Mom, I'm going out for a bit!" Deryn yelled to her from the front door. "Be back by 10!" she yelled back.

She took my coat and then secretly stashed her knife , a gift from her dad, and then walked towards the tree in the neighbourhood park. She then made sure no one and beastie was watching before she unsheathed her knife and took her anger out onto the poor tree.

She continued this for about 5 mins, when she sensed another presence behind her. Taking the knife out of the tree, she hid it behind her back and turned around. What she saw kind of surprised her. Balancing on a thin pole from the jungle gym was the boy form last night. He clearly has some amazing balancing skills to stand on there without slipping. But that wasn't what she was focusing on. The boy has silky auburn curls, big piercing emerald eyes holding coldness that of someone who knows death and has long eyelashes like a girl. He was really pale but only his lips were a dull pink. He was He wore a white dress shirt that was un- tucked that fitted perfectly onto his slim body and a pair of black jeans , also a cross necklace around his neck with also a crimson red tied around his neck. (you know, the collar and stuff, like those ribbon neckties. To describe him, handsome didn't fit it, it was more like beautiful. Maybe prettier than that stupid Sylvie.

The only thing she could utter was "Aren't you cold without coats or boots?" 'That was such a stupid statement!' she thought to herself.

"I forgot how it feels like to be cold long long ago." He replied smoothly like a high class aristocrat. He looked upon me like I was some object in a museum. To start a conversation, she asked "How Old are you and whats your name? My name is Deryn Sharp and I'm 16 by the way." He once again answered, " You may call me Aleksander fer- or Alek. No last name. I am 16 as well."

Aleksander, sounds like a noblemen's name. She wonder if he and I can be friends.

Just like reading her mind, he said again "We cannot be friends. Friendship will never form between us." and then he hopped down from his former position. Embarrased, Deryn shouted the only thing I culd think of. "W-well, whoever said I wanted to be your friend either?" Then she ran back towards my house which clearly was just across the street. When she reached my front door and looked back towards the park. He was gone.

Deryn ran back inside and ignored my mother's voice., quickly changed into her PJs then dove into bed. Staring at the ceiling in the dark, she thought about the strange kid, Aleksander until she finally fell asleep.

…

OMG that took me a long time. If Alek seems a bit ooc to you, then I'm sorry. But he'll act into character later. I was also listening to the song "continued Story" from code geass and everything sounded so dramatic. Some of the historical facts aren't accurate since this is a world where there are Darwinists and clankers. Please review!
