Snow

“I was desperate. I had to keep Annabeth alive. I imagined all the bubbles in the sea—always churning, rising. I imagined them coming together, being pulled toward me.
The sea obeyed. There was a flurry of white, a tickling sensation all around me, and when my vision cleared, Annabeth and I had a huge bubble of air around us. Only our legs stuck into the water.
She gasped and coughed. Her whole body shuddered, but when she looked at me, I knew the spell had been broken.
She started to sob—I mean horrible, heartbroken sobbing. She put her head on my shoulder and I held her.
Fish gathered to look at us—a school of barracudas, some curious marlins.
'Scram!' I told them.
They swam off, but I could tell they went reluctantly. I swear I understood their intentions.
They were about to start rumors flying around the sea about the son of Poseidon and some girl at the bottom of Siren Bay.”
