Annabeth sat on the beach watching the tides flow in and out. He should be here by now.


For the past few weeks, Percy had been away, on vacation to Montauk beach with his mom. He said he would be away for three days, max. He had even invited her, but she had declined, as she wanted to oversee the building if the new cabins. She had Iris-messaged him, but she got no answer. Annabeth was getting very impatient. Something was probably wrong. She pulled a golden drachma out of her pocket, throwing it into the rainbows made by the sea spray. "O Iris, Goddess of the Rainbow, please accept my offering. Show me Sally Jackson." Mrs. Jackson's worried face appeared in front of her.

"Annabeth! How are you? You must be very worried. I tried to contact you, but I had run out of drachmas, if you can believe that!"

Annabeth laughed, her nervousness seeping away. "How's Percy?"

"Ah, yes. I meant to tell you. A great sea monster has come, and it can also go on land. And only a child of Poseidon can defeat it, not even Poseidon himself."
