Disclaimer- If I owned Percy Jackson or Harry Potter, I wouldn't be sitting here writing this fanfiction, I would be working on the next book or movie in my series. (Right, Rick and Jo?)

*The timelines in this story will NOT match up with canon. It is impossible for my main character to be the same age as Albus Potter and Rose Weasley, but I want her to be, so she will be. I will also be changing some of the ages of the Weasley/Potter children for the purposes of this story.*

*PS- The Cursed Child never happened*

It was a warm, sunny day at Camp Half Blood. I was sitting in Cabin 6, the Athena cabin, an open book about various Greek monsters sitting in front of me.

I just remembered that you have no clue who I am. Allow me to introduce myself. Cara Black, daughter of Athena. Well, my real name is Carina, but don't call me that unless you have a death wish. I got here at camp when I was 8, and have been here for almost 3 years now. Also, I turn 11 tomorrow, on August 26.

The cabin was quiet, since a majority of my siblings were out helping rebuild the camp. Of course, according to them, I'm "too young" to be a help. Sometimes, my older sister, Annabeth, snuck me out and let me help, though.

Ah, my sister Annabeth. She was the best sister any girl could ever ask for. She never underestimated me because of my age, and that's probably because she herself got here at a young age.

I was always an outcast in the Athena Cabin. While a majority of my siblings had blonde hair, I got stuck with mom's dark brown hair. Thanks, mom. That wasn't the only thing that separated me from my siblings. Children of Athena weren't supposed to have special abilities. Our powers were our brains. But, yet again, I was different. I made things break when I was mad. I made things fly to me when I wanted them. I made sparks fly from my hands when I felt threatened, a mystery that even us Athena kids couldn't solve.

Back to the point. Annabeth was one of the few people that truly accepted me. Some of my other siblings did as well, but I had always felt closest to her.

Speak of the devil, here she is.

"Hey Cara. What're you reading?"

"Just a random book on Greek monsters."

"Oh, that's cool. Never can be too prepared. But I was just wondering if you were up to helping me with my blueprints for Olympus?"

I don't even know why she bothered asking. I adored helping her design Mt. Olympus.

"YES!" I then ran to her desk with all of her blueprints laid across it with her laughing behind me.

We then worked for the rest of the day, and managed to decide how we wanted the entrance. I was so tired by the end of it that I plopped down on my bed and fell asleep without even touching my book. (A real shock for us Athena kids)

I woke up the next morning with the realization that it was my birthday. I looked around my cabin and saw that nobody was there. Well something's up… I immediately thought.

I changed into my orange CHB shirt and walked down to breakfast. I then looked at the empty Athena table.

Subtlety at its finest… Something is so up…

I ran towards the Athena table and sat down. Then, a mass of people jumped from around me and yelled "SURPRISE! HAPPY BIRTHDAY!"

"Y'all definitely didn't make that obvious." I stated, but had a huge grin plastered on my face.

Suddenly, an owl swooped down and landed on the table, right in front of me. I didn't think that much of it at first, considering who my mom was. But little did I know that that owl would change my whole entire life.
