Hi i'm new. but i love the series!

Percy woke up. He sat up, rubbed his eyes and looked around. He was infront of two huge metal doors with a giant gray metal wall wrapping around something giant. the walls were huge, maybe as tall as a house. He stood up and looked at his clothes, he wasn't wearing a shirt, but he was wearing bathing suit trunks. weird. He tried to think about where he was, but strangely he couldn't think of anything. He couldn't remember his name, where he was, who he was, where he came from, nothing. He realized he was wearing a neclace with a few beads on them. He studied them when finlly one made his heart sink. He didn't understand why though, he read the names, Charlie Beckandorf, Silena Bouragard, Michael Yew. He knew these people. He was scared where was he? He decided to knock on the doors. He waite about a minute before someone started to open the door. It was a girl, she had black hair and hazel eyes, she was kinda cute, but the weird thing was, she wearing armour and percy could see a knife at her side. "uhh.. sir, im sorry, this is.. uhmm Dakota!" Another girl came to the door she was spanish and had brown eyes and blonde hair, she was even prettier then the first girl. The girl dakota looked strangely at Percy up and down. "Must be a mortal" she whispered to the first girl. "yeah, i think your right, but how do i get rid or him?" "ill take care of it" dakota siad. Uhm i'm sorry sir you must be lost. Listne this is a summer camp. "why are you guys wearing armor" percy asked."uhm.. hazel, he can see us whering armor" "i know thats weird". "Are you uys demi-gods"? Percy had no idea why he asked that, he didn't even know what that is."are you?" the girl Hazel asked. "i think i am. but i don't remeber anything! just the armor looks familiar". "you can't remember anything? thats weird". "But i know for a fact im a demi-god, ive been called that before. i know it." "uhmm.." "PROVE IT." the girl dakota yelled. without even thinking Perc dug his hands into his pocket, he felt around them, and pulled out a piece of paper and a pen. no, it wasn't a piece of paper, it was a picture. Percy studied the picture, it was of a girl, she was gorgeous, he could tell he had no make-up on. She had grey eyes and blonde hair. Percy felt a strong connection to her, and he knew she was one of the most important things in his life. He shoved the picture back in his pocket and looked at the pen, it had greek writing on the side that he translated to Riptide. He clicked the pen. It grew into a 3 footed sword. But Percy wasn't suprised, he didn't exacly understand how a pen became a sword, but he some how knew it was going to happen. Hazel and Dakotas eyes went huge. They stared at the sword then at Percy. "how.. how.." Dakota took out her sword, "fight me". "uh.. i don't really remem-" before Percy knew it she slashed at him he blocked and slashed at her aiming for her arm, he cut her. They kept fighting but Percy knew what to do. He blocked, slashed, hit, rolled until he had Dakota at her throat.
