Artemis- Back as the Primary Personality

Artemis woke some time later with the smell of singed flesh in his
nostrils. He knew he was back in the real world because of the harness
digging into his shoulders and the choppy motion of the sea, which
was making him nauseated.
He opened his eyes and found himself looking at Foaly’s rump. The
centaur’s back leg was kicking spasmodically as he battled sleep
demons. There was music playing somewhere. Familiar music.
Artemis closed his eyes and thought, That music is familiar because I
composed it. “Siren Song” from my unfinished Third Symphony.
