DISCLAIMER: The Percy Jackson books are creation of Rick Riordan and sadly not me.
"Alexandria!" Poseidon yelled at me, "Come here, NOW!"
"What?" I yelled back from my room in the top of the tallest tower of the underwater kingdom, my voice carried by the water.
"Come here!"
"FINE! I'M COMING!" I jumped out of my window and floated down to him.
"Come with me," he said, as I landed. I didn't move.
"Am I in trouble?" I asked him.
"No, but your brother is."
"He's right here though," I said, confused and pointing to Poseidon and Amphitrite's son, my half-brother, Triton.
"No, not him, you twin brother, Perseus."
"WHAT? Did you say TWIN?" I yelled at him.
"Yes, your twin. You're a half-blood, Alie, and you'll be going to Camp Half-Blood with him."
Okay, so this I kind of more of a prologue but hey! Oh, and Alexandria never knew she was a half-blood, just kind of a minor goddess 'cause she lived with her dad. Just sayin!
