“It's okay,” he said. “We're together.” He didn't say you're okay, or we're alive. After all they'd been through over the last year, he knew that the most important thing was that they were together. She loved him for saying that.”

His face was white with effort. She could see in his eyes that he knew it was hopeless.
"Never," he said. He looked up at Nico, fifteen feet above.
"The other side, Nico! We'll see you there. Understand?"
Nico's eyes widened. "But-"
"Lead them!" Percy shouted. "Promise me!"
"I-I will."

Percy tightened his grip on Annabeth's wrist. His face was gaunt, scraped and bloody, his hair dusted with cobwebs, but when he locked eyes with her, she thought he had never looked more handsome.

"As long as we're together," she said.
She heard Nico and Hazel still screaming for help. She saw sunlight far, far above- maybe the last sunlight she would ever see.
Then Percy let go of his ledge, and together, holding hands, he and Annabeth fell into the endless darkness.”
