I woke up screaming and in a cold sweat. "Darcy, you ok?" Percy asked. I told him I was fine, but that was a lie. "Hey, I know what will make you feel better, a trip to the beach!" he said.

Was he serious? I guess so because he grabbed my hand and led me to a beach. He handed me a light blue swimsuit and I put it on behind a tree. Percy hopped into the ocean while I laid in the sand.

"Hey Darcy!" Percy called. I sat up and took off my sunglasses. "Yeah?" I said. "Come in! The water's great." He said. My heart pounded. "Umm… No thanks." I said. "Oh! C'mon. I'll make sure you're safe. I am a son of Poseidon after all! I'm the safest person you could go into the ocean with." He smiled. "Ok, fine." I made my way over to the ocean. It was a little above my ankle when I started to panic. Her body could be in the sand! I turned to walk away but Percy grabbed my hand. "Percy, LET GO!" I yelled. He looked out to the ocean. "Listen, I'm going to do my son of Poseidon thing. And you're not going to freak out."

I was really worried now. I decided to tell him about my fear. "Percy, I have a… AAAAAAHH!" Percy had grabbed my hands and now had me riding a wave with him. I screamed and screamed as loud as I could, but he either couldn't hear me or didn't care. I was starting to wish I had gone in the Athena cabin with Annabeth. All of the sudden the wave stopped and we fell into the water. I opened my eyes.

The weird thing was I could see perfectly. Percy smiled and waved. Then, a totally weirdonkulus thing happened. I didn't need air. I stayed under for like, 10 minutes. I still didn't need to go back up. I can't be breathing underwater, I thought, that's inhuman! But I was. Then Percy let out a girlish squeal.

We swam up to the surface. "OH MY GODS! I HAVE A SISTER!" he screamed. "What?" I said. Me? A daughter of Poseidon? No way. I was afraid of the water! Poseidon must have it wrong. I looked up. A glowing blue trident was above my head. Percy grabbed my hand and we rode a wave all the way to shore. The blue trident was struggling to keep up.

He made the wave go away and we ran back to camp. "I have a sister! Darcy is my little sister! OH MY GODS! OH MY GODS!" He ran around the camp holding me and screaming his head off. The blue trident was still above my head. Soon, the whole camp was out here. They were cheering. Annabeth came running out. "No way!" she gasped. "YES WAY!" Percy yelled. The blue trident disappeared and Percy hoisted me up onto his shoulders.

A girl from the Ares cabin walked over. "Clarisse, look! I have a little sister!" Percy said. "Oh. Yay. Percy junior. Another one." She looked up to the sky. "Why?!" she stormed away to her cabin. Everyone walked over to breakfast.
