Percy felt like every molecule in his body was spontaneously combusting. Yeah, he thought,big words for a Seaweed Brain like me. His body was screaming in agony and all he wanted to do was die.
Then he remembered. His so called Achilles heel. He started remembering what Annabeth had told him about battle strategy. The small of my back, Percy thought. It'll be hard to hit if I'm wearing armour.
Suddenly, everything started to come back into focus, the world sharper, not as fuzzy.
An image appeared of Annabeth. They were in the labyrinth and she had kissed him. Then he realised.
I love her.
Then Percy waded out of the river into the musty atmosphere of the Underworld.
