~PERCY~
I woke up covered in sweat and panting heavily. I looked outside and saw that it was still pitch black outside.
Meanwhile, my mind was in overdrive.
No way. There is no way that the baby I saw in my dream could be my...my sister. I forced the last two words out.
But the evidence is right there! A voice argued with me.
I shook my head in silent denial. The dream had to be a mistake.
I quickly got up and walked out to my cabin out to the place where I could always think more clearly.
The Long Island Sound.
I sat on the beach as my head began to spin.
I don't get it. Why would he...? When did he...? I felt a mixture of anger and hurt built inside of me.
You see, deep down, the truth was: I didn't mind having another relative. After all, Frank was awesome. He was one of my closest friends. And even Tyson, my Cyclops half-brother, wasn't so bad.
But Frank was a distant relative. And Tyson was a Cyclops.
This girl was both a demigod AND my half-sibiling, which made it different somehow.
I knew that the gods and goddesses weren't faithful. Why do you think demigods had so many siblings? However, it was still kind of painful, knowing that my dad had loved my mom, and had even told her he would let her live in his palace with him, only to meet someone else.
I wanted to hate my sibiling, but I didn't.
I remembered her struggling for life, and the cold Roman goddess, and I remembered it wasn't her fault this had happened.
Once the hate I tried to muster disappeared, another million questions entered my head:
How old was she? What did she look like? What was her mom's name? Did she know she was a demigod? Who-
My train of thought was interrupted by someone's voice.
"Percy?"
I turned and saw Annabeth looking at me with a look of sleepy confusion on her face. I tried to grin, but I could only managed a weak sigh. Of course, having spent so much time with her-and having known her for so long, she read my facial expression like an open book.
I took a deep breath and said:
"I have another sibling. A demigod sibling."
