The story will not start at Camp Halfblood but it will get there after the first couple of chapters. This also takes place after The Last Olympian but before The Lost Hero. Also, I know Percy disappeared during winter break but for the purpose of this story we're going to pretend that he doesn't disappear until the next winter break. Thanks for reading! Please review!

Her lungs burned like someone had set them on fire and her feet hurt from running so long. All Cassie McDonald wanted was a comfortable chair and a glass of water and she'd be content with life but she couldn't stop not with the dark creature chasing her. She knew she didn't have much longer until it reached her but she still ran like she had a chance.

Cassie was too busy being scared and tired to see the rock in her way but she felt her foot slip and her ankle crack. She let out a quick moan of pain. She watched as the black, dinosaur sized dog-looking thing slowed to a walk because it knew that she didn't have a chance. It kept coming closer and it might as well have been walking death. It was twenty feet away. Fifteen. Ten. As it neared five feet Cassie had decided to give up and hope that the creature would kill her quickly. But just as the creature got to three feet away and was about to eat her Cassie heard a voice. It was soft and feminine. Cassie wasn't sure that she had heard it. It was a whisper in the wind and it said:

"Don't give up."

Those simple words flooded Cassie with new strength. She was drunk on adrenaline and was in a daze as she stood on her feet but didn't feel the pain of her injured ankle. From her pocket Cassie drew her only thing that could be used as a weapon. It was a silver pocket knife that her grandpa had given her for her fifteenth birthday two days ago. It had been Cassie's grandpa's before he gave it to her. On the handle his name, Jerry, was engraved on it.

There were three options in this particular knife they were scissors, a file, and a regular knife. At least that's what Cassie thought the options were but when she unsheathed the knife the blade grew and the handle became leather bound. Cassie found herself holding a full-length sword. Cassie spent three precious seconds that she could have spent getting ready for the oncoming monster gaping at the weapon but a crack of a stick jarred Cassie from her shock.

Cassie, not ever have held a sword before, felt her hands shake as she held the heavy sword but she luckily didn't drop it. She held the weapon up as the creature, at the sight of the weapon being raised against it, picked up its pace.

As the creature charged Cassie instinctively closed her eyes. She felt her sword go through the monster even if she didn't see it. As she opened her eyes the only thing she saw left of the thing was a pile of dust. Cassie couldn't process how she killed it or what had exactly happened but the only thing she could figure was that the thing had built up too much momentum to dodge the sword and then somehow turned to dust.

As Cassie's brain wandered to all the possible explanations for the creature she made her way out of the woods and to the road. She looked around and couldn't see anything she recognized. Cassie lived in this area with her grandpa for most of her life. They lived in a small cottage that Cassie's grandpa had built himself. Cassie didn't have any friends other than her grandfather because she was homeschooled and their cabin was isolated.

As Cassie continued to walk she remembered the reason she had left her home in the first place, to find her grandpa. She knew he was kidnapped or his dead body was buried somewhere but she didn't know where.

Cassie would've told the police if their town had a police force but since it didn't Cassie was forced to look for help herself. She had only gotten a few blocks before the huge creature had found her. Then she ended up in her present situation too bad she wasn't quite sure what that situation was.
