This is a story that's going to have quite a lot of chapters. I might even have a sequel to this. Do you guys prefer long chapters and less frequent updates? Or shorter chapter and more frequent updates? This is my first real story that isn't just a one or two-shot, so please let me know if there's any mistakes in here! Also, Alyssa is an OC of mine. She might appear in future stories/one-shots. If people want, I might make a story about Alyssa's past, how she became a Ranger, etc. I hope you don't mind me switching POV's randomly xD

NOTE: Something happened with the formatting. There isn't indents at the beginning of all paragraphs, I apologize for that. I don't know how to fix it.

Anyways, hope you enjoy! :)

Leo's POV

It was a normal summer day at Camp Half-Blood. Everyone was enjoying the warm sun. I, on the other hand, was in the forest where we normally played Capture-The-Flag. The forest was one of the few places where I could think. The quiet sounds of nature calmed me down in times of stress.

I sat down on a mossy boulder and thought about the events that had happened during the last few months. Percy and Annabeth had recovered successfully after the fall into Tartarus. The Doors of Death were closed. But that's another story.

Life at camp hadn't changed one bit. If anything, I felt more of an outcast than ever. Percy and Annabeth were spending a lot of time together to compensate for the time lost while they were in Tartarus. Everyone else was always spending time with their significant other.

My siblings didn't pay much attention to me either. I was the one that spent sleepless nights building the Argo II. I was there when everyone needed me most. But no one was ever there for me.

A loud, vicious, roaring sound jerked me back to reality. My hand instinctively dropped to my magical tool belt and pulled out a large hammer. I spun to my right, where I heard the roar.

I slowly made my way towards the sound. It was normal for monsters to lurk in the forest. But I wanted to slay it before it got the chance to sneak up on me later on. After a minute of winding in and out between the trees, I saw a black hellhound the size of a school bus. I also saw...a girl. What was a young girl, no older than me, doing here in the middle of the woods, alone? I've never seen her around camp before, I suspected she would be a new addition to our camp very soon.

The girl was desperately trying to avoid the hellhound's razor-sharp claws and deadly teeth. My battle reflexes took charge. I charged toward the monster, shooting a column of fire at it's face. The hellhound howled in pain and swung its head to the offender. I hefted the hammer over my hand and brought it down in a deadly arc on its black paw. The beast once more snarled in pain and lunged at me, those razor-sharp teeth ready to snap up its prey.

I was ready for it, and rolled to the side, the deadly teeth missing me by inches.

I willed another column of fire to shoot from my hand, this time hitting the hellhound in the side. I shot a quick glance back where I last saw the girl, sure enough, she was leaning against a tree, favoring her injured leg.

The hellhound tried me again, raising a clawed paw to lop my head off. I jumped back, quick enough to avoid being beheaded, but not quick enough that one of the claws scraped my stomach. The scar when from the left side of my ribcage, down to my right hip. I could feel warm blood slowly seeping through my shirt as I winced in pain.

I slowly advanced to the hellhound, only then realizing that the beast was in no better condition than I was. It was limping from one of its paws that I had smashed earlier. Its face and side was charred and burned.

I bit my lip and tried to ignore the pain that seared through me. Apparently the wound was cut deeper than I thought.

I took a deep breath and barreled to the hellhound, raising my hammer over my head, and I brought it down on the monster's skull with a sickening crunch. The beast instantly disintegrated into monster dust.

I turned to the tree where the girl sat. I sprinted to her and knelt down at her side. The girl was matted with recent and dried blood, all over her body. She donned simple brown leggings and a matching brown shirt. At least, I assumed they were brown. I couldn't be sure due to all the mud and dirt and blood that was smeared over her clothing. On her feet were soft leather boots, and she also had a large bow and an empty quiver strapped to her back. A ripped green-grey mottled cloak completed her outfit. Her head was lolled to one side, her shoulder-length, tangled auburn hair sprawled across her face, masking her eyes.

I put a finger on her wrist to check her pulse. It was there, but it was faint. I figured she wouldn't have long to live unless she got proper medical care. The girl's head slowly moved at the contact of my warm skin. Her head lifted, shaking her hair off her face, and a pair of deep brown eyes met mine.

"What...w-who are you...?" she stuttered, in a barely audible voice.

"I'm Leo Valdez. Don't worry, you're safe now. We need to get you some help. Fast!"

"L-leo..." Her voice faded and her head lolled to the side again.

With renewed urgency, I picked her up bridal-style and made my way out of the forest to the infirmary, dodging the low-lying branches on the way.

I broke out through the trees and sprinted to the infirmary. She was fairly light, so I had no problem carrying her. Campers looked at me questioningly, but I simply ignored their attention.

I burst through the open doors of the infirmary. "I need help! Quick!" I yelled, my voice carrying to every corner of the room. Several patients glared at me for the disruptment. I shrugged and gently laid the girl down into a soft, white cot. One of the Apollo kids, which I recognized as Will Solace, rushed forward. He immediately checked her pulse, and his brows furrowed as he frowned. "What happened?" Will asked calmly, grabbing some ambrosia off a nearby table.

I proceeded to tell Will what had happened. He nodded slowly as he the absorbed the information. "She's alive," Will began. "But only hanging by a thread. I'm positive that she's a demigod. Otherwise, she wouldn't have been able to cross the camp boundaries, nor would she have been attacked by that monster in the first place. And by her condition, it looks like she came across several other monsters as well. I'm impressed that she made it alive without a guardian satyr."

3rd Person POV

Leo watched as Will carefully used a linen bandage to wrap around the girl's head, stemming the blood flow. He gently prodded her ribs, arms and legs, and found two broken ribs and a broken ankle, along with cuts and bruises in between. Then, he broke off a piece of the ambrosia and gently fed it to her. Will stood up, brushing the remaining ambrosia crumbs off his hands. Will noticed the blood stained on the front of Leo's shirt. He handed Leo a square of ambrosia, which Leo accepted gratefully, and Will carefully placed a bandage around the wound. Leo thanked Will and hurried off to the Big House to alert Chiron of this situation.

Chiron opened the door to his private study to reveal a certain son of Hephaestus. Leo started babbling incoherent words as soon as he saw the centaur. "There'samysteriousgirlthatIfoundbeingattackedinth eforestandIbroughtherintotheinfirmaryandshe'suncon scious," Leo explained, rather louder than necessary.

"Woah, slow down there! Take a deep breath. Now tell me what happened. Slowly," Chiron said calmly.

Leo took a deep breath and started over. "Chiron, just a few minutes ago, I was in the forest. And all of a sudden I heard a monster. So I searched for it and saw a hellhound attacking this...girl. She was around my age, maybe even younger. There was no one else around, so I killed the monster. She was in bad shape, all bruised and cut up. She was barely conscious when I rushed to her side. Before I could ask for a name, she slipped into unconsciousness. So I carried her to the infirmary, where she's being taken care of by some of the Apollo kids."

Leo suck in a deep breath, waiting for Chiron to say something. He just simply nodded, taking in all the new information. There was an awkward silence between the two, as Leo looked anxiously to the centaur for some sort of answer. After a minute of dead silence, Chiron finally spoke, his voice grave.

"Well, she's in good hands for now. We'll question her further when she wakes up. I appreciate your bravery in standing up to the hellhound to save her life. But for now, you may go back to your regular activities."

And with that, Chiron dismissed Leo, who headed off in search of the seven to tell them the news.

"So, if she is a demigod, who do you think her godly parent is?" Percy wondered aloud.

Leo had called the seven demigods for a meetup. And here they were, sitting on the beach.

Everyone looked expectantly at Leo, and he shrugged.

"I'm just guessing here," Leo began. "But when I found her, she had a bow, so maybe she's the daughter of Apollo?"

Piper furrowed her eyebrows, deep in thought. "Just because she has a bow, doesn't mean she's Apollo's kid. Frank uses a bow, and he's a son of Ares," She pointed out.

Leo nodded slowly. "True. But Ares is the god of war, so technically, Frank doesn't count..." Leo countered.

Annabeth rolled her eyes in exasperation. "Oh for gods' sake, do we have to argue about this?! We'll find out eventually who her parents are. In the meantime, let's just make her feel welcome," Annabeth suggested. She scanned her eyes among the demigods, each one nodding and chorusing their agreement. They were smart enough to know not to annoy a child of Athena, especially Annabeth. They all stood up, brushing off the sand from their clothes, and went to resume their normal activities. Leo was left standing on the beach, still curious about the mysterious girl.
