Summary: Nico is the leader of a coven of vampires, but his sire and the other older vampires are not very pleased by his leadership because he lets a pack of werewolves live in his city. So to show the Old Ones that he's not soft, he takes some wolves captive. But werewolves don't like it when you take their own captive. So they decide to take revenge by turning the one human Nico desires into a werewolf. What is Percy, who would have never believed supernatural beings to exist, supposed to do, now that he's not only a submissive werewolf, but also has a horny vampire leader at his heels? And why is a group of so called hunters also after him...?

The Beast Within

Between Two Sides of the Moon

Prologue: The Story of Starfall Hollow

In the darkness of the deepest night sat a lone figure. A man of youth, at least in appearance. A man of wealth. And a man of power. His deep, dark eyes were staring thoughtful into the wine glass in his hand, though the red liquor within was by far not wine.

"You look thoughtful, brother mine", murmured a soft, female voice from behind him.

"You already arrived?", hummed her brother in reply, not lifting his gaze.

Lightning illuminated the sky behind them. The young woman, merely twenty years from the looks of it, laughed softly and pushed her long, black curls over her shoulder. She walked up to him to place her head on his shoulder.

"Hazel let us in. Thalia and the others are getting adjusted. I thought I'd first check on my little brother", smiled the woman. "Reyna voiced her concerns about a village boy you seem quite interested in. Tell me about him, Nico."

"A village boy?", snorted Nico, turning to stare at her ridiculed. "This is not the eighteenth century anymore. We don't say it like that. He's a boy from school. With quite captivating eyes."

"He's a boy from this village, which makes him a village boy. Don't be a wise-ass, Nico", chided his sister irritated. "Reyna said it's more than just his captivating eyes. She said you're thinking about turning him. Is that true?"

"Perhaps", shrugged Nico and put his glass down. "But that's none of your concerns, Bianca. You're not part of my coven. You have your sire to report to and I have mine. And my business is exactly that. It's mine. If I chose to turn him to make him mine, then I will do that. I've spend enough time alone. It's time I find someone to rule beside me."

"I had hoped you would have done so when you turned little Hazel in the 30s", sighed Bianca.

"Gross", snorted her younger brother and wrinkled his nose. "She is like a sister to me. I turned her because my realsister abandoned me."

His dark eyes darkened even more as he glared at the other. "I didn't abandon you. I followed Thalia. She is my sire-sister. And she is my mate. It's not my fault we did not get turned by the same, Nico. It's not my fault Luke chose you."

"Oh, don't mention him", muttered Nico with a grumpy look. "He promised to visit with the others. Not much of a promise, more so a threat."

"The others?", yelped Bianca wide eyed. "You mean to say that the Old Ones will come here?"

"It's the reason I asked Thalia to come", nodded her brother. "I need your help and advise."

"Why are they coming?", hissed Bianca with dialed eyes. "And when?"

"There is this pack of mutts living in my forest", drawled Nico a bit bored. "I think Luke is not happy that I let them live there."

"Why are you letting them live?", growled his sister irritated. "The least any vampire needs is an angry Oldest at their heels! Especially when you're thinking about changing someone! Oh, Nico!"

"Don't throw a fuss", muttered Nico. "Go and rest. We'll have a big lunch tomorrow and I plan on showing you my city. It'll be eventful and nice."

"Well... Yes", sighed Bianca defeated and leaned in to kiss his cheek. "Don't be reckless, Nico."
As she left and the door fell close behind her, he turned back to the high windows to stare at the stormy sky. The storm fit his mood so perfectly tonight.

"I'm not reckless", whispered Nico thoughtful. "I know exactly what I'm doing. And Percy Jackson will be mine. With or without Luke's agreement."

"This is it?", grunted a mid-twenty blonde a bit irritated.

He sat behind the wheel of his car. A simple, plain model to not draw attention. The blonde girl, late teen, looked at the map in her lap and nodded shortly. The blonde boy on the backseat leaned forward to take a look for himself.

"Yep, Octavian. We're here", confirmed the boy. "It's Starfall Hallow."

"And we're sure he's here?", asked Octavian, turning a bit to look at the male teen.

"Well, Austin. You have the file. Take a look", grunted the girl a bit irritated. "All I want is a diner with a proper toilet. If I have to go into the woods one more time, I may go crazy. This has to be it. I'm tired of traveling through the state."
The boy, Austin, muttered something beneath his breath before checking his backpack, pulling a file out and opening it. The first thing he saw was a picture, a photo of a teenage boy with black, unruly hair and bright, sea-green eyes.

"Starfall Hollow", nodded Austin. "After his mother died in a car accident, child protective services got him away from his abusive stepfather. He got adopted by a couple, the Underwoods. Residents of Starfall Hollow. They're already taking care of two foster children named Ella and Tyson. It seems they're okay. Mortals, I mean. Normal folks."

"And we're one hundred percent sure about his heritage, Kayla?", asked Octavian, snatching the photo away from Austin.

"A hundred and ten percent", nodded the girl with a smirk. "I stole some evidence from the car accident where his blood was on and checked it myself. He's the son of Poseidon Jackson. He has the right blood. He's one of us."

"A born hunter", smirked Octavian, staring intensely at the photo. "Well then. It's time to get to know him a bit better."

"No funny business, Tavy", warned Kayla with one raised eyebrow. "I know that predatory look."

"He's cute", shrugged the oldest of them. "Perhaps I'll find my very own way to make him part of our team. Now come, lunch will be my treat."

"Yes!", exclaimed Kayla and Austin with broad grins.

A Latino boy, maybe sixteen years old, sat alone on a bench in front of the high school, staring off into the distance. He heaved a sigh, his hands shoved deep into his pockets.

"What are you looking all depressed for, Leo?", asked a mocha-skinned girl curiously.

She sat down on the back-rest of the bench, ruffling his hair curiously. Leo blinked a few times before looking up at her with his head tilted to one side like a curious puppy.

"It's nothing, really", hummed the Latino, shaking his head. "Don't worry about me, Nyssa."

Nyssa huffed and rolled her eyes, taking a look around. "We're all alone, Leo. All others already left to get back to our pack. You know you can talk to me, right?"

"Well... okay...", nodded the boy slowly, a bit awkwardly, his arms wrapped around his knees. "It's just that I saw Frank and Hazel earlier, you know when Frank had football training and I happened to... uh... be around... And... ah, damn, you know..."

"Yes, I know that you have a death wish", snorted Nyssa slightly irritated, hitting him upside the head. "We can be lucky that Alpha Beckendorf has a treaty with di Angelo's coven, but I doubt that the big boss vampire will be very happy to learn that you drool over his most trusted 'family' member. You know how much he values his 'little sister'. What you're doing is suicide. Not to mention that they are vampires and you are a werewolf. Look, you know I love you like that annoying, little brother I never had, but it pains me to see how you're making yourself suffer like that. You deserve better than that."

"You have no idea, Nys", sighed Leo, resting his forehead against his knees. "Percy had said something similar earlier too. That it's no use pining after a couple."

"See!", interrupted Nyssa enthusiastically. "Even an ordinary human knows that you're fighting a lost battle there! How about you just listen to us, huh?"

"He may have said that", continued Leo, turning his head to glare at her briefly. "But he's mistaken. And so are you. You two have no freaking idea how it is to be me!"

She scoffed and rolled her eyes, ruffling his hair again. "Oh yes, the torturous existence of Leo Valdez. You know you're not the first male submissive. And those before you did survive without attempting suicide by vampires, right?"

"Suppose you're right", shrugged the Latino and stood. "Guess I'm just overall useless. Even as a submissive wolf. Let's get back home, Clarisse will roast us anyway for being late."

"You're not useless", chided his friend, nudging him as they slowly left the school. "You just haven't found the right dominant for you. But one day, you'll find the perfect wolf, okay?"

He shrugged and nodded, keeping to himself that he didn't want a wolf. He wanted his vampires.
