Author's Note: The sisters are Hermione and Annabeth. Set after MCGOA and DH. I couldn't wait for the third book because I was too excited to write this so bear with me if there are mistakes that don't make sense in cannon. I am trying to stick as close to cannon as possible.

CHAPTER ONE: The Truth

Hermione POV

It had been almost two years since the war. I had just finished my seventh year that I went back to Hogwarts to finish it properly. It was August and I was chilling in my room reading The Lord of the Rings when my mother called me. Now before we get to why she called me, a few things to tell you. My parents had forgiven me about the whole erasing their memories. They understood why, but were a bit miffed that they couldn't have helped me. If you're wondering why I'm just reading in my room instead of working on something, finding a job, thinking about my future, or somehow go to more school, it's because I honestly would just like a break. A break from the work, stress, action, and drama. Anyways back to the story.

Curious, I put my book down and walked down the stairs to see both my parents looking anxious and also guilty. I frowned at their expressions wondering why they would look guilty.

My father sighed, "I-We haven't been honest with you honey."

At that comment a hundred things ran through my mind. What came next was nothing that I expected.

My mother started at barely a whisper and gradually talked louder. "We… we aren't you're real parents. We adopted you." They gave me a minute to comprehend before continuing. "You're parents gave you to us when you were seven. I do not know why, although I have a theory. Your father was a muggle or well more like a squib. Your grandmother was a witch. Your mother, ah how should I put this. Your mother is… she's a-"

"Your mother is Athena, the Greek goddess of wisdom and battle." Cut off my father.

I scoffed, "Named after the goddess?"

"No, Hermione. The Greek dieties are real."

I normally would've asked if this was a joke or a prank, but their faces told me they were dead serious. I instead asked, "Do I have any siblings?"

My mother answered as if prepared for the question. She probably was. "If you mean full, as in having both the same parents. Yes. You have a sister named Annabeth who is the same age as you. Well almost. She is only a couple of months older and her birthday is in July. If you meant half, which is having only one of the same parents, also yes. You have over twenty."

"If I was given to you at seven, than why don't I remember and why did they give me up?"

"We don't know that so you'd have to ask your parents. Recently, we have been in touch with your father and if you and your sister agree, then we will set up a meeting for you guys to meet each other. I think your sister and father are having the same conversation right now. So would you like to meet your sister and father?"

I thought about it. I mean I would love to meet my sister but I was also confused. I decided to think about it.

Annabeth POV

"What?!!" I glared at my father and then proceeded to the sky. "And you just decided to erase a sister from my life?"

"We didn't erase her."

"Oh really?" I challenged sarcastically. "So erasing both our memories about each other and giving her to a family on the other side of the planet and lying to us both isn't erasing her from our lives?"

My father started to say something then stopped. He apparently thought of something else to say, "It wasn't like I wanted to! It's just-"

"It's just Mrs. Chase, " I ephasized the last part, "wanted you too, so you acted like the pet you are and did what you were told. Fine, but why erase our memories?"

"We thought it would stop you from running away."

"And so obviously it didn't, so can we have our memories back?"

"Well I can't do that. You'd have to ask-"

Before he could finish, my mother Athena showed up. She barely looked at me as she asked, "Are you sure you want to?"

I stared straight into her piercing grey eyes and nodded. Abruptly, a stream of memories flowed through my mind. Even though I prepared myself for it, I fell on one knee. When I recovered, Athena was gone and my dad was looking at me in pity. I was done with my parents right now. I walked out of the house without casting a second glance.
