Annabeth heaved a sigh, wondering where could possibly be,
she had searched all of New Rome for him, when it suddenly hit her. She
sprinted as fast as she could to his apartment.

“Percy?” she called out tentatively as she pushed open the
door to his apartment. There was no response.

“Percy? Are you in here?” Annabeth tried again as she
stepped inside, still without an answer.

“Percy?” she whispered in disbelief – the apartment was
completely empty and looked as though he had never been there. He was gone. Again. ‘What have I done?’ she thought, close to tears, ‘Is he all right? Where is he? Who did this?’ a thousand questions raced through Annabeth’s mind at lightning speed. She couldn’t answer any of
them but she knew one thing for sure: no one messed with her Seaweed Brain and
who or whatever did this was going to be very, very sorry.

This is basically my prediction for 'The Crown of Ptolomy. (is that spelt right?)
