My name is Cassandra McQueen, everybody call me Cassy though. I’m a daughter of Poseidon and yes, Percy Jackson was my half-brother. We never know each others’ existence until last summer before I turned fourteen, a guy –I later found out was a satyr– came to our house to pick me up to bring me to a summer camp, which was not new to me since my mom always enrol me to a summer camp ever summer. Like most demigods, my mom never told me who my father was, only that she had a short-live affair with him. She said that they met after he watched her performance on a musical play in West End. My mom was British but after I was born we moved to New York, where she continued her career as a Broadway singer.

I can’t believe how my life suddenly took a one hundred eighty degree in a matter of months after finding out what I really am. It was a lot to take in at first; to find out I’m a demigod, my father was Poseidon the god of the sea and I had a half-brother. But with Percy and his girlfriend, Annabeth’s help, I was able to quickly adapt being a demigod. And Percy? He was the older brother I’ve always wanted to have, but I’ll never ever say that to his face. He was very easy to get along with and very funny too.

I remember the night I was claimed by our father, he was grinning at me like he was really happy to have me as his half-sister. Later that night we walked down the beach to have a brother-and-sister-get-to-know-each-other bonding time. For the first time since I arrived in Camp Half-Blood, I saw him looked serious.

“You didn’t look surprise when I was claimed by Poseidon.” Not that I don’t want to call him dad, it just felt weird to call someone you never know and never believe exist to call as my father.

“It’s your eyes.” Percy said like it was very obvious. “A year ago dad told me that he’ll send me brothers and sisters next summer. I thought he was only kidding.” He told me.

“Because you don’t like to have another brothers and sisters?” I asked.

He looked down at me and it suddenly struck me how our sea green eyes were so alike, a thing we both inherit from our father but aside from that we don’t have anything else in common when it comes to physical appearance. While he had a hair as black as a raven’s feather, my hair was as white as snow, forming a halo like illusion around my head.

“No, I actually enjoy having a sibling. You had another brother Tyson, he’s a Cyclops and often come here to visit me but right now he works for dad.” He said with a small smile as if remembering our brother.

“A Cyclops?” I repeated, my facial expression must be a mixed of disbelief and horror because he laughed at me. “They are monsters, right?” I thought he was making fun of me.

“Yup, for both of your questions.” He answered. “You’ve got nothing to worry about though, Tyson’s great brother. I’m sure he’ll be very happy to meet you.” He assured me. I just nodded then we walked in comfortable silence as we go back to our cabin.

Percy was walking me to the subway after I ate dinner with his mom, stepfather and him at their house (They live in Manhattan while my mom and I live in Queens), when were about to walk pass an alley we heard a commotion followed by a blonde teenage boy that wore all black flipping through the air, and landing right in front of us, his back facing us. The guy must be a demigod or a gymnast to be able to do such stunt, not to mention gracefully.

Percy hastily moved in front of me, keeping himself between me and the blonde boy. I saw him draw out riptide out of his pocket ready to uncap it any second now. In reflex, my hand immediately flew and gasped the trident pendant of my necklace, my weapon that turned onto any weapon I want it to be; it was a gift came from my father. The boy seemed to not notice us or he didn’t care about us standing there beside him. He pulled out a dull tube like dagger from his belt that holds more weapons.

“Asariel.” The boy called out at that instant the blade of the dagger he was holding glowed brightly, blinding Percy and I for a moment. Then the boy dashed back into the alley, where we saw him came out.

This time Percy uncapped riptide, turning the ballpoint pen to a Celestial Bronze sword. I also tugged my necklace and commanded it to turn to a sword. He glanced back to me and asked, “Ready for some action, little sis?”

I nodded then we both run after blonde boy. It was one of the things I really love about my brother, even though he was protective of me he will never tell me to stay on the sidelines because he trust me that I can take care of myself and it was in our nature, to fight.

In the alley, there was a small group of monsters with claws and there were jets of flames from their empty eye sockets. I never saw monsters like this before, even illustrations in books back in camp. Blonde boy was slicing and stabbing the monsters efficiently like he’d been doing it his whole life and maybe he does.

Percy seemed to not care about not recognizing those monsters; his natural warrior instinct simply took over, probably telling him to just kill the monsters. I also didn’t waste any more time figuring out what was their name and sprang into action. I have never been into a quest but I’ve fight my fair share of monsters and my brother personally trained me, so I can say that I’m a good fighter.

The monster tried to claw me but I chopped its hand and cut the head then it just vanish without turning into sand, which confused me more. I didn’t have the time to think about what those creatures were, another monster that jump at me. I rolled to the side away from it then quickly went back to my feet and run straight to the monster. I stabbed it in the spine, just like the other one it just vanished leaving no trace of its existence.

I looked around me; there were only the three of us in the alley now. I noticed that my brother and blonde boy were sizing up each other now that there were no monsters left.

“Thanks for intruding my demon hunting.” Blonde boy told us, his words dripping with sarcasm.

“You’re welcome.” Percy replied with the same tone casually shrugging his shoulder.

“Demon?” I repeated. Believing in myths is one thing but demons? My mind was racing with many questions.

“Don’t tell me you didn’t know what is the thing you just killed was?” He asked us in complete disbelief.

“They were monsters.” Percy automatically answered.

Blonde boy laughed like it was the most hilarious thing he heard in awhile. “In a way they were, but the right term is demon.” He corrected him. “You are not a mundane since you can obviously see me and can kill those demons. I don’t think you’re downworlders either. What are you? ”

“What’s a mundane? Downloaders, like a person who download something from the internet? And of course we can see you we are not blind.”

Blonde boy smiled as if remembering a funny memory. I went to my brother’s side and tugged at the sleeve of his shirt, he glanced at me and our eyes met, silently conversing how we should handle the situation.

“Mundane means normal and he said downworlders not downloaders.” I whispered to him and he nodded.

Blonde boy was not a demigod that’s for sure. I remember Percy telling me about the boy he met before that talked about Egyptians and the possibilities of another set of gods out there. What if this boy was also from different world from ours?

It seemed like it sunk in to Percy that this boy was not a demigod and thinking about the same thoughts as me. “Look, we didn’t mean to get involve to your mons– demon hunting. We’re just in the wrong place at the wrong time. It’s for the best if we just forget this night happened.” He said to blonde boy, uncapping riptide to turn it back to a pen and I did the same turning my weapon back as a necklace to show blonde boy were not a threat and telling the truth.

“Want to stay mysterious, so you get to see me again, huh?” Blonde boy smirked cockily. I find it hard to read whether he was joking or he was just really cocky.

“That is exactly what we’re trying to avoid.” Percy said, tucking his hands inside his jeans.

“And here I thought everybody find me charming.”

“Sorry but I’m straight.”

“I don’t like boys.” I replied, which was true but I won’t deny that blonde boy was indeed charming, enchanting even.

“News flash I’m a boy.” My brother pointed out.


“Well, I don’t have much choice but to like you, do I?” I said. “Anyway, let’s just go.” I started to drag my brother out of the alley. I don’t think blonde boy will attack us, for some reason I trust him not to harm us.

*****

We reached the subway station; Percy hugged me tight then ruffled my braided icy white, hair to annoy me. “Quit doing that!” I complained.

“Have a safe trip.” He told me after he let me go.

“You too, I don’t think blonde boy will easily give up knowing who we are.” I voiced out my worry.

“I know.”

“Should we tell Chiron or Annabeth about what happened?”

He shook his head. “I don’t want to worry them. Let’s keep it to ourselves for awhile.”

“Maybe we should investigate about it.” I said, excitement was cursing through me with the thought.

“Not unless he becomes a threat, until then we’ll leave him alone.” He said authoritatively.

“Okay.” I said a little disappointed. “I should get going, mom must be getting worried.” I waved goodbye to my brother and went inside to go to the platform area.

Notes

A/N: Hi! Thank you for reading my story! You have no idea how much that means to me! What do you think of my story? I know I’m not the best writer but I’m trying to improve. English is not my first language and I know it’s not an excuse but please bear with me!!! ^_^

About Cassy: I always wanted Percy to had a half-sister because Jason had Thalia and Nico had Hazel, he is the only son of the big three that didn’t have a sister in the series, so I think it will be cool if he also had one.
